Photonic RF signal generation

[CANDIDATE THESIS, unvalidated] Photonic generation of RF/mmWave carriers displaces electronic frequency-multiplier synthesis as the preferred low-noise, widely-tunable source above ~40 GHz for satellite comms, 6G and high-end test.

The callPhotonic oscillators are far cleaner than electronic ones above 40 GHz, but the physics has worked since 2000 and the buyers still have not shown up.

Fig. 1The balance. Drivers and catalysts against restraints, each block sized by its weight; catalysts hang dashed because they have not happened yet, sized by their odds. It tips toward the restraints.
  1. D1Radio moves into D-band and satellite feeder links, and above about 40 GHz electronic multiplier chains get noisier with every step, capping data rate and radar range.
  2. D2Two programmes, GRYPHON and an ESA contract, have moved photonic sources from lab demonstrations toward a deployable part.
  3. R1Buyer urgency is missing: OEwaves has shipped photonic sources since 2000 and stayed niche, and Freedom Photonics sold to Luminar for about $34.6M.
  4. R2The deep money funds primes and labs; GRYPHON's performers are Honeywell, BAE Systems and Caltech, and the 6G clock keeps slipping with WRC-27 and Release 21.
  5. C1A photonic frequency generator flies as the working oscillator on a commercial comms payload, the first flight design-in beyond qualification contracts.2031
