We present an analysis and optimisation of optical resonant cavity enhanced (ORC) long wavelength Hg₁₋xCdxTe photovoltaic detectors operating at near room temperatures. The resonant cavity is based on Hg₁₋xCdxTe Bragg reflector and detector heterostructure grown on a GaAs substrate, supplied with a metal back reflector. Such devices are compatible with low-temperature epitaxial (MBE and MOCVD) techniques. The optical gain due to ORC enhancement was calculated for the ambient temperature and the temperatures achievable with two-stage Peltier cooled 10.6 um detectors as a function of the device design and an incidence angle.
