Coverage: Partial inventor search
One attributable semiconductor-waveguide family was inspected, with Hebrew University/Yissum as original assignee and Levy/Shappir/Goykhman co-inventors. US20170176780A1 and WO2015151110A3 are indicated as variants, not separately counted. Patents merely citing Desiatov’s optical papers, including the Stanford nonlinear-optics technology lead, were not treated as his inventions. Harvard-era coverage remains incomplete.

Published patent document inspected
Publication assignee: Yissum Research Development Co of Hebrew University of Jerusalem
The inspected inventor field names Boris DESIATOV. Exact rare name, semiconductor-waveguide field and Levy/Shappir/Goykhman team match the baseline publication record from Hebrew University-era work. Author citations in other patents are not inventorship. Assignee means the observed original-assignee field; no current ownership conclusion.[339]
Original evidence: not verified
No attributable patent record was verified in the bounded search.
Records are counted separately from identified families. Author-reported entries are labelled and may still need publication verification. Inventorship, publication-time applicant and current ownership are different facts. No legal-status, patentability or freedom-to-operate conclusion is made.
Scores prioritize research fit from 1–10; they are not probabilities.
Review: Reviewed with limitations
Proposed capability matches, not confirmed relationships. Scores are analyst judgments with low forecast confidence; researcher interests, capacity and feasibility need confirmation.
10 candidates
Connection 1
Original proposal
Proposal hypothesis: Blau's frequency-domain quantum transformations and Desiatov's integrated nonlinear conversion have a direct mode-control/device division of work.[37][38][135][136]
Proposed first test: Model a three-mode transformation on a specified nonlinear platform and compare fidelity, cross-talk and fabrication-tolerance sensitivity.
Rank 1/10; fit 9/10 (4 topic overlap + 3 complementarity + 2 feasible first test). Preserved original co-membership proposal in o10. No strictly higher-scoring candidate displaces this original. High optical topic fit still requires a platform-specific loss budget before a fabrication commitment. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.
Analyst proposal hypothesis, not an established collaboration, commitment, evidence-confidence rating or assessment of researcher quality; confirm participation and access before work.

Rank 4/10; fit 9/10 (4 topic overlap + 2 complementarity + 3 feasible first test). New pairing outside the frozen portfolio co-member graph. Closely related photonic roles limit complementarity; cascading devices may worsen loss. Equal scores use existing-first, then stable researcher ID.

Proposed first test: Model one reported emitter spectrum through a thin-film nonlinear converter and compare conversion fraction, noise assumptions and insertion loss.
Rank 5/10; fit 8/10 (3 topic overlap + 3 complementarity + 2 feasible first test). Preserved original co-membership proposal in o10. An added candidate, Moti Fridman (9/10), ranks above this original because its stated pair-specific roles and first test score higher; this original is limited as follows: Material integration and source purity remain unverified; modelled frequency conversion is not proof of a usable single-photon device. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.

Rank 8/10; fit 7/10 (2 topic overlap + 3 complementarity + 2 feasible first test). Preserved original co-membership proposal in o10. An added candidate, Moti Fridman (9/10), ranks above this original because its stated pair-specific roles and first test score higher; this original is limited as follows: Quantum-foundations expertise alone does not establish a fabrication-compatible sensing advantage. No automatic score boost for original membership. Equal scores use existing-first, then stable researcher ID.

Connection 1
Harvard University
Original proposal
Harvard documents Loncar's nanoscale-optics and quantum-engineering work, closely complementing Desiatov's integrated nonlinear photonics; prior coauthorship means this is an expansion hypothesis rather than evidence of a new relationship.[135][136][137][470]
Fabricate or model a small device array and measure process variation, conversion bandwidth, loss and repeatability before any sensing-performance claim.
Rank 1/10 after semantic revision; analyst score 9 = max(1, 4+3+2): topic overlap 4/4, complementarity 3/3, feasible first test 2/3. The experiment, numerical inputs or identity/scope needs confirmation before execution. Original remains first under these components; original status breaks equal-score ties only, without a prestige bonus.
Proposed fit, not an assertion of a new or active relationship. Independent review pending; forecast confidence low. Partner interest, capacity, data access and any required experimental approvals/resources are unverified. The accepted original portfolio o10 describes Desiatov-Loncar coauthorship; this proposes an extension, without asserting a current joint project.
