Abstract :
We studied the Selective Area Growth of AlGaInAs Multiple Quantum Wells for wide wavelength range applications such as Coarse Wavelength Division Multiplexing. A 3-D vapor phase diffusion model is used to simulate the complete set of mask patterns. Due to high mask density, the long-range effect of Ga and Al compared to In species is a limiting parameter for the total achievable wavelength extension. Based on these simulations, we predicted and experimentally obtained a total PL wavelength shift of 240 nm.
