Abstract
Photonic generation of frequency-modulated continuous wave (FMCW) based on period-one (P1) oscillation of an optically injected semiconductor laser (OISL) is numerically investigated. A modulated optical injection can drive an OISL into P1 oscillation for generating an FMCW signal, and an optical feedback is further introduced to reduce the phase noise of the generated signal. The influences of operation parameters on the performance of the generated FMCW signal are discussed. The numerical results show that under proper operating conditions, a photonic FMCW signal with a sweep range of 12.41 GHz can be obtained. After adopting optical feedback, the frequency comb contrast can be increased to a level more than 30 dB.
