摘要：
A compact optical-microwave phase detector is proposed and its performance is evaluated by synchronizing an 8-GHz oscillator to a 250-MHz mode-locked laser. The residual out-of-loop phase noise at 1 Hz and 100 kHz offset are -115 dBc/Hz and -146 dBc/Hz respectively. And the RMS timing jitter is 600 as when integrated from 100 kHz to 1 Hz. The proposed phase detector has a compact structure and is easy to implement using all commercial devices to achieve subfemtosecond synchronization between optical pulses and microwave oscillators.
