Özet

Alternative material systems on InP substrate provide certain advantages for mid-wavelength infrared (MWIR), long-wavelength infrared (LWIR) and dual band MWIR/LWIR quantum well infrared photodetector (QWIP) focal plane arrays (FPAs). While InP/InGaAs and InP/InGaAsP LWIR QWIPs provide much higher responsivity, when compared to the AlGaAs/CaAs QWIPs, AllnAs/InGaAs system facilitates completely lattice matched single band MWIR and dual band MWIR/LWIR FPAs.
