Frequency-modulated continuous-wave (FMCW) can be acquired by using a distributed feedback semiconductor laser (DFB-SL) operating at period-one (P1) oscillation under an optical injection modulated by a Mach–Zehnder modulator (MZM). In this work, through introducing another MZM to establish cascade-...
