Abstract

We propose and demonstrate a technique to stabilize pulse generation based on gain-induced four wave mixing (FWM) via injection locking with no feedback. Robust and low-phase noise pulse generation was achieved. Pulse-train generation from 230 MHz to 76GHz with a linewidth of 1Hz is experimentally demonstrated. The injection locking effectively narrows the linewidth of the generated pulse by four orders of magnitude. The fiber ring cavity reduces the sideband phase noise by 100 times and suppresses the residual injection signal by three orders of magnitude.
