Fig. 1: [a] Experimental configuration of the CFBG-SPML laser. EOM, electro-optic modulator; CFBG, chirped fiber Bragg grating; FP, Fabry–Perot etalon; SOA, semiconductor optical amplifier; DCF, dispersion compensated fiber. [b] Electronic drive pulse provided to the EOM. [c] Round-trip times for cavities A, B, and AB. [d] EOM and SOA modulation signals [upper panel] were used to suppress light circulation in short cavities A and B, while allowing circulation in cavity AB [lower panel].
