hQphotonics President and cofounder, Dr. Jiang Li, gave a 30-minute invited talk on Field-deployable, ultra-low phase noise photonic microwave oscillators at the 2022 International Topical Meeting on Microwave Photonics (2022 MWP): https://attend.ieee.org/mwp-2022/full-programme/

Invited Paper Abstract (#TU2.1, 2022 MWP): In this paper, compact, ultra-low phase noise (ULPN) photonic microwave oscillators at 10, 20, 30 and 40 GHz based on electro-optical frequency division (eOFD) are described. At 40 GHz a record-low phase noise of -153 dBc/Hz is achieved (10 kHz offset, 40 GHz carrier). The oscillators use typically 50W wall-plug power from a single 12V supply.

Paper Abstract:
A 30 GHz ultra-low-phase-noise oscillator is demonstrated using electro-optical frequency division. The measured phase noise is -151 dBc/Hz (10 kHz offset) and -109 dBc/Hz (100 Hz offset). Phase locking to an external reference for long term synchronization is also demonstrated.
