Millimeter-wave generation reached -148 dBc/Hz phase noise at 1 MHz offset on a 111.45 GHz carrier.
Self-injection locking of two diode lasers to a micro-Fabry-Perot significantly simplifies wave generation architecture.
Photonic measurement techniques enable effective characterization of low phase noise at high frequencies.
This compact system could advance telecommunications and sensing applications by reducing size, weight, and power requirements.
