Abstract
The strain-balanced InAsP/lnP/lnGaAs multiple quantum well (MQW) structures for mid-wavelength-infrared photodetectors are presented. The MQW consists of +2% strained InAsP wells, InP barriers and -2% strained InGaAs layers, where the strained lnP/InAsP/lnP quantum wells provide a light-absorbing layer and the strain is entirely compensated by introducing thin strained InGaAs layers.
