The objective of the study is to design and simulate a external cavity laser(ECL)using a given reflective semiconductor optical amplifier(RSOA) with silicon photonic reflectors, and adjust to meet the technical requirements. In this paper, we show a design of a ECL using the SAF1126C RSOA with a Bragg grating as reflector, with the goal of achieving an output wavelength of 1550 ± 1nm , good wall-plug efficiency, efficient optical output power and be able to operate at 2.5Gb/s.
