We report the growth and fabrication of bound-to-bound In0.53Ga0.47As-InP quantum-well infrared photodetectors using metal-organic vapor phase epitaxy. These detectors have a peak detection wavelength of 8.5 μm. The peak responsivities are extremely large with Rpk=6.9 A/W at bias voltage Vb=3.4 V and temperature T=10 K. These large responsivities arise from large detector gain that was found to be gn=82 at Vb=3.8 V from dark current noise measurements at T=77 K and gp=18.4 at Vb=3.4 V from photoresponse data at T=10 K. The background-limited temperature with F/1.2 optics is TBLIP=65 K for 0b≤3.4 V. The highest value of peak detectivity is Dλ*=5.4×109 cm√Hz/W at Vb=2.9 V and T=77 K, while for TBLIP=65 K, the background-limited detectivity, which exhibits negligible bias dependence, is DBLIP*=3×1010 cm√Hz/W.
