Optical Phased Array Technology 2026 — PatSnap Eureka
Optical Phased Array Innovation: The 2026 Patent & Research Map
Solid-state, electronically steerable OPAs have reached a pivotal inflection point — driven by autonomous vehicle LiDAR, satellite FSO communications, and defense directed-energy applications. Explore who is filing, what they are protecting, and where the white space lies.
How Optical Phased Arrays Work — and Why They Matter Now
Optical phased arrays operate by routing coherent light through networks of waveguides, applying controlled phase shifts at each channel, and emitting through an antenna array such that constructive and destructive interference in the far field steers a beam to a desired angle — directly analogous to microwave phased-array radar but operating at optical wavelengths. The core technical challenge is achieving full 2π phase control per element at sub-wavelength spacing while maintaining low insertion loss, broad wavelength bandwidth, and scalability to thousands of elements.
The technology has reached a pivotal inflection point in 2025–2026, driven by demand from autonomous vehicle LiDAR patent analytics, free-space optical communications, and directed-energy defense applications. Among retrieved results, the technology spans at least five distinct sub-domains: photonic integrated circuit (PIC) OPAs on silicon and III-V platforms; MEMS-actuated OPAs for wavelength-independent phase control; liquid crystal and metasurface OPA implementations; non-redundant and circular array architectures for wide field-of-view; and defense-oriented free-space OPAs with atmospheric turbulence compensation.
The foundational patent portfolio dates back to Hughes Aircraft Company filings in Israel around 2000, with the modern integrated PIC era commencing with MIT's nanophotonic array work covered by an EP patent issued in 2018. Standards bodies including WIPO and the EPO have tracked increasing cross-border filings in photonic integration since 2018.
Four OPA Innovation Clusters Shaping the 2026 Landscape
Patent and literature analysis via PatSnap Eureka reveals four dominant technical clusters, each with distinct IP ownership patterns and commercial trajectories.
CMOS-Compatible Silicon Photonic Integration
The dominant approach involves fabricating OPA chips on silicon-on-insulator (SOI) or silicon nitride platforms using CMOS processes, enabling mass manufacture of arrays with hundreds to thousands of antennas and on-chip phase shifters (typically thermo-optic or electro-optic). MIT's EP patent (active, 2018) covers CMOS-fabricated nanophotonic antenna arrays with directional coupler-based evanescent coupling. Shanghai Jiao Tong University demonstrated SOI-based OPA with 0.8 µm pitch curved waveguide arrays achieving aliasing-free steering across ±32° field of view.
Key assignees: MIT, Samsung, SJTUMEMS-Actuated Phase Shifting
MEMS OPAs achieve wavelength-independent phase shifts by physically displacing grating elements laterally, circumventing the inherent wavelength sensitivity of refractive-index-based thermo-optic or electro-optic phase shifters. University of California's 2019 work demonstrated a 160×160 element array over a 3.1 mm × 3.2 mm aperture with 0.042°×0.031° beam divergence and 5.7 µs response time, achieving approximately 25,600 independently controllable pixels. Eindhoven University's InP platform demonstrated 70 nm tuning range for spectral imaging.
Key assignees: UC, Eindhoven, UT AustinNovel Array Geometries: Circular and Non-Redundant
To overcome the grating-lobe limitation of conventional uniform linear or rectangular arrays — which requires sub-λ/2 element spacing — researchers have developed circular topologies and non-redundant array (NRA) configurations. Optiwave Systems' concentric-ring OPA with 820 elements achieves 0.22° beamwidth and greater than 10 dB sidelobe suppression. Carleton University's 820-element circular OPA achieved a steering range of 0.51π sr solid angle. The University of Tokyo's NRA concept enables quadratic scaling of resolvable points with antenna count N, versus linear scaling in conventional designs.
Key assignees: Carleton, U Tokyo, Optiwave, HoneywellDefense-Grade and Free-Space Communication OPAs
High-power and long-range OPA applications require closed-loop compensation for atmospheric turbulence, integration with low-SWaP platforms, and wavefront sensing co-integration. Rafael Advanced Defense Systems' IL patent (active, 2024) replaces deformable-mirror/wavefront-sensor architectures for high-power free-space laser illumination through turbulent atmosphere. SRI International's JP filing (pending, 2025) targets inter-satellite optical links using diamagnetically levitated actuators. X Development's JP patent (active, 2025) integrates photodetectors within the OPA combiner tree for real-time wavefront sensing.

Four Signals from the Most Recent OPA Filings
The four most recent filings in this dataset (all 2024–2025) collectively signal three emergent technical directions and one enabling capability shift.
OPA-Integrated Wavefront Sensing for Closed-Loop FSO
X Development's 2025 JP patent embeds photodetectors within the OPA combiner tree to perform real-time wavefront error measurement on the same PIC used for beam steering. This represents a convergence of sensing and steering functions on a single chip, moving OPA beyond a transmitter-only device into a transceiver module with inherent channel estimation.
Actuated OPA Telescopes for Low-SWaP Satellite Links
SRI International's 2025 filing replaces heavy gimballed mirrors with diamagnetically levitated actuators combined with OPAs having reduced phase-shifter count. This low-power actuation paradigm targets the rapidly growing low Earth orbit satellite constellation communications market, with the filing explicitly referencing Starlink-class systems with large relative motion between nodes.
What the OPA Patent Landscape Means for IP Strategy in 2026
LiDAR remains the dominant commercial pull, but the satellite communications opportunity is accelerating. R&D teams should note that X Development and SRI International are staking IP positions in OPA-based FSO communications (2025), suggesting this market is entering a pre-commercialization IP filing phase analogous to where automotive LiDAR was in 2017–2019. The PatSnap materials and photonics intelligence platform can help teams track these signals as they emerge.
Platform choice is a critical fork: silicon PIC vs. III-V vs. MEMS. MIT's CMOS-silicon platform (EP active) covers a broad foundation, while Eindhoven's InP and UT Austin's InP/InGaAs work establish III-V territory for broadband and mid-IR applications respectively. IP strategists entering the space must audit freedom-to-operate across both platforms — a task suited to PatSnap's IP analytics tools.
Circular and non-redundant array geometries represent white space for IP capture. Work from Carleton University and the University of Tokyo on circular and NRA topologies has been published in literature (2021–2022) with limited corresponding patent filings identified in this dataset, suggesting an underprotected innovation cluster that product developers could formalize. Industry bodies such as Optica (formerly OSA) have published extensively on these topologies.
Defense applications (Rafael, directed energy; SRI, satellite) are driving closed-loop atmospheric compensation innovation. This creates a potential dual-use technology transfer pathway: closed-loop OPA turbulence compensation developed for defense could migrate into ground-to-satellite commercial FSO links, where the same wavefront distortion problem exists.

Optical Phased Array Technology — Key Questions Answered
Optical phased arrays (OPAs) are solid-state, electronically steerable beam-forming devices that manipulate the phase of light across an array of emitting or receiving elements to direct coherent beams without mechanical movement. They operate by routing coherent light through networks of waveguides, applying controlled phase shifts at each channel, and emitting through an antenna array such that constructive and destructive interference in the far field steers a beam to a desired angle — directly analogous to microwave phased-array radar but operating at optical wavelengths.
The dataset reveals a bifurcated landscape: a small number of large commercial entities (Samsung Electronics, Honeywell, MIT/spin-offs) hold broad platform patents, while a significant volume of specialized architecture and performance innovations comes from academic groups (Carleton University, University of Tokyo, Shanghai Jiao Tong University, Eindhoven University of Technology, Zhejiang University, University of Texas) and defense contractors (Rafael, SRI International).
The technology spans at least five distinct application domains: autonomous vehicle LiDAR (the largest commercial driver), free-space optical communications and satellite links, defense and directed energy applications, mid-infrared sensing and spectral imaging, and near-eye displays and structured light for AR/VR systems.
CMOS-compatible silicon photonic OPAs fabricate chips on silicon-on-insulator (SOI) or silicon nitride platforms using CMOS processes, enabling mass manufacture of arrays with hundreds to thousands of antennas and on-chip phase shifters (typically thermo-optic or electro-optic). MEMS OPAs achieve wavelength-independent phase shifts by physically displacing grating elements laterally, circumventing the inherent wavelength sensitivity of refractive-index-based phase shifters. This approach enables wideband operation at the cost of higher fabrication complexity.
Circular and non-redundant array geometries represent white space for IP capture. Work from Carleton University and the University of Tokyo on circular and NRA topologies has been published in literature (2021–2022) with limited corresponding patent filings identified in this dataset, suggesting an underprotected innovation cluster that product developers could formalize.
National University of Defense Technology's 2023 work on Ultra-Compact and Broadband Nano-Integration Optical Phased Array uses AI-assisted inverse electromagnetic design (3D-FDTD optimization) to create T-branch splitter trees with 500 nm bandwidth and −0.2 dB insertion loss — directly addressing the lateral dimension bottleneck that has limited large-scale OPA chip integration.
