Abstract :
We demonstrate reduced photodetection noise floor of a 10 GHz fiber laser-based photonic microwave generator by using a pulse repetition-rate-multiplier in combination with a modified Uni-Traveling-Carrier (MUTC) photodiode that features high power handling and linearity. This enables a residual phase noise floor of -170 dBc/Hz at 10 GHz, which is a 5-25 dB improvement over earlier results. Photodiode flicker noise is measured to be near -133/f dBc/Hz.
