Abstract :
A one-dimensional finite-difference time-domain (FDTD) simulator for ultrafast GaN/AlN intersubband photonic devices is described. Ultrafast response measured in a GaN/AlN ridge waveguide has been successfully reproduced by the simulator, taking the influences of background loss, inhomogeneous broadening, and 2-dimensional mode profile into consideration. The simulator was also utilized for feasibility study of intersubband optical amplifiers.
