Resonant cavity enhanced HgCdTe structures have been grown by molecular beam epitaxy, and photoconductors have been modelled and fabricated based on these structures. Responsivity has been measured and shows a peak responsivity of 8 x 104 V/W for a 50 X 50 μm2 photoconductor at a temperature of 200K. The measured responsivity shows good agreement with the modelled responsivity across the mid-wave infrared window (3-5μm). The measured responsivity is limited by surface recombination, which limits the effective lifetime to ~15ns. The optical cut-off of the detector varies with temperature as modelled from 5.1 um at 80K to 4.4 um at 250K. There is strong agreement between modelled and measured peak responsivity as a function of temperature from 80-300K.© (2006) COPYRIGHT SPIE--The International Society for Optical Engineering.
