This paper discusses experimental and theoretical studies of the efficiency of optical coupling in GaAs/AlGaAs multiple-quantum-well-infrared photodetectors (QWIPs) via optical diffraction grating. Optical responsivity has been studied to compare the effectiveness of different grating structures fab
We report the use of intermixing techniques to modify GaAs/AlGaAs multiple quantum wells (MQWs). A large shift in the response wavelength of the GaAs/AlGaAs MQW-based infrared photodetector is obtained by proton implantation and then a standard annealing procedure (950 โข C for 30 s). The photolumine
We study the optical transition between bound-to-continuum states in a GaAs/AlGaAs multiple quantum well infrared photodetector (QWIP) by analyzing three possible boundary conditions for the continuum states. Comparing with experimental results, it has been suggested that the Bloch-state boundary co
