Microwave Extraction Based on Synchronization of Ti:sapphire Optical Frequency Comb and Optoelectronic Oscillator

SummaryWe demonstrate a highly stable microwave extraction method based on the synchronization of an optical frequency comb generated by Ti:sapphire mode-locked laser and microwave generated by an optoelectronic oscillator. The absolute phase noise of locked OEO at a carrier frequency of 2 GHz, reaching -92 dBc/Hz at 20 Hz and -141 dBc/Hz at 100 kHz.
