2D simulation of a buried-heterostructure tunable twin-guide DFB laser diode
Tóm tắt
A 2D simulation of an InGaAsP-InP buried-heterostructure tunable twin-guide (TTG) DFB laser diode is performed. The device structure is optimized with respect to maximal tuning range and output power. To minimize the current leakage around the active region, a p-n-p-n current blocking region is also modeled and its effect on the laser characteristics is discussed. Good agreement between simulation and measurements is obtained.
