摘要：

We demonstrate 9.192 GHz microwave signals from photonic microwave generation based on Er:fiber-based optical frequency combs and 1.55 mu m ultra-stable lasers, which used for local oscillators of cesium fountain clock. The frequency instability of the 9.63 GHz/9.54 GHz microwave signals is 3x10(-15)@(d 1s, with phase noise is of -94 dB rad(2)/Hz @ 1 Hz, and the synthesized tunable 9.192 GIIz signal exhibits an instability of 6.7x10(-1)(5)@1s. Further improvement of the photonic oscillators is undergoing.
