Abstract

Results of detector characterization are presented for quantum well infrared photodetectors (QWIPs) fabricated from a variety of III-V material systems lattice-matched to InP substrate. Extremely large responsivities of 33.2 A/W were obtained from GaInAs/InP QWIPs operating at (lambda) equals 9 micrometers which represents to the authors' knowledge the largest value of responsivity for any QWIP in this wavelength range. Devices made from AlGaInAs/InP and GaInAs/AlInAs have also been realized that extend the wavelength range of sensitivity from 3 micrometers out to 20 micrometers while remaining lattice-matched to InP. Lattice-matched multispectral detectors are demonstrated for sensitivity at both 4 micrometers and 8.5 micrometers . Localized epitaxy of GaInAs/InP superlattice structures lattice-matched to InP was performed on Si substrate for the purpose of monolithic integration of III-V QWIPs with Si-based readout integrated circuitry.
