Silicon Photonics Dense Integration Patent Snapshot 2026
The Silicon Photonics Dense Integration field is in a Growth stage, with multi-year filing volume significantly above prior periods, though annual output has eased from its 2022 peak. The corpus is highly concentrated: Raytheon Co dominates as the single largest filer, with the top five applicants collectively accounting for almost three-quarters of the leading filers’ combined activity.
Raytheon leads a tightly held, early-stage corpus
With 15 patent families in scope, Silicon Photonics Dense Integration is a nascent, highly concentrated field. Raytheon Co holds the top position with 6 patent records, well ahead of the nearest rivals — Neye Systems Inc, Nokia of America Corp, and the Regents of the University of California — each with 3 patent records.
The top five filers collectively represent 74% of the ranked applicants visible in this query’ combined total, signalling that a very small set of organizations has defined the early IP contours of this space. A meaningful academic and start-up presence (University of California, University of Toronto, GL Bajaj Institute of Technology & Management) sits alongside the two visible commercial players.

Raytheon’s lead, rooted entirely in optical elements and systems (G02B 6), suggests a defense-adjacent systems orientation. The challengers’ broader multi-class footprints — Nokia of America covering lasers and stimulated emission (H01S) in addition to optical systems, and Neye Systems focusing on optical waveguide integration — point to differentiated technical strategies rather than direct head-to-head competition.
The most recent filing years (2024–2026) are likely under-counted due to standard patent publication lag and should not be read as indicative of declining activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2022 surge defines the growth arc; optical elements dominate the technology mix
Filing activity and technology composition together reveal a field that mobilized sharply around 2022 and remains overwhelmingly focused on optical waveguide and systems engineering, with adjacent semiconductor-device and transmission branches only lightly explored.
Annual filing trend
Annual filings were negligible from 2017 through 2021 (at most one per year), then surged to 5 records in 2022 — the field’s peak year — before settling at 4 in 2024. The 2025 and 2026 figures are understated by publication lag and should not be interpreted as a real slowdown. On a multi-year basis, recent-period filings are dramatically above the prior window (+450%), confirming a Growth lifecycle stage.

G02B (Optical Elements & Systems) accounts for 18 of the technology branch records, making it the overwhelmingly visible IPC class in this corpus. H01S (Lasers & Stimulated Emission) follows with 4 records. H01L (Semiconductor Devices) and H04B (Transmission, General) each register just 1 record, underscoring that photonic integration at the device and system-transmission layers remains a relatively unexplored area within this landscape.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Raytheon Co
Raytheon Co leads with 6 patent records, all concentrated in G02B 6 (Optical Elements & Systems). Its momentum is classified as a new entrant within the recent filing window, indicating that all of its filings emerged in the most recent period rather than building on a prior base. The single-class focus suggests a systems-integration or defense-sensor orientation rather than a broad photonics platform strategy.
patent records: 6Nokia of America Corp
Nokia of America Corp holds 3 patent records and demonstrates the broadest technology footprint among the top filers, spanning G02B 6 (Optical Elements & Systems), H01S 3 (Lasers & Stimulated Emission, gas/other), and H01S 5 (Lasers & Stimulated Emission, semiconductor). This multi-class coverage implies an integrated photonic transceiver or laser-waveguide co-design approach, distinguishing Nokia from Raytheon’s pure optical-systems focus. It is also a new entrant in momentum terms.
patent records: 3Frequently asked questions
The in-scope corpus contains 15 patent families. This is a small, early-stage corpus reflecting the field’s nascent commercial trajectory.
Raytheon Co leads with 6 patent records, approximately double the count of the nearest challengers — Neye Systems Inc, Nokia of America Corp, and the Regents of the University of California, each with 3 patent records.
The field is classified as Growth. Recent three-year filings are 450% above the prior three-year window, confirming multi-year expansion. Annual volume peaked in 2022 and has eased since, but the most recent years are further suppressed by publication lag and should not be read as a structural decline.
Europe (EPO) is the leading filing jurisdiction with 6 patent records, followed by the United States and WIPO (PCT) with 3 records each. India and Singapore each hold 2 records, with Canada and Malaysia holding 1 each.
Yes. The only documented co-filing relationship in the evidence is between Neye Systems Inc and the Regents of the University of California, who jointly filed 3 patent records. No other collaboration pairs are identified in the corpus.
The most-cited work in the corpus is titled ‘Multi-frequency hybrid tunable laser,’ which has received 12 citations. The evidence does not provide assignee or publication number details for this document.
