Abstract

We propose and experimentally demonstrate a method to generate 10-GHz and broadband optical frequency comb by novel stretch-type time-lens rather than nonlinear effects in actively mode-locked fiber laser. Injection locking and feedback loop have been used to suppress super-mode noise and help stabilize the optical spectrum. As a result, a comb that 20-dB bandwidth equals to 8nm and phase noise lower than -120 dBc/Hz in beat 10GHz microwave signal is achieved.
