Also, we have dynamic analysis of. the tunable laser based on laterally coupled semiconductor optical amplifier and laser diode. This structure is simulated by using the coupled mode theory and the modified time-domain transfer matrix met-hod. The simulation result yields a tuning range of 48 nm with a side mode suppression ratio around 35 dB.
