In conclusion we have presented an RCE-HPT heterojunction phototransistor with an MQW absorber that is tolerant to inhomogeneous and homogeneous variations in layer thicknesses. Arrays show good uniformity as well as record high responsivities. The standard deviation of a typical array is 1.1 nm in resonant wavelength and 13.3 A/W in peak responsivity. This is significantly smaller than the FWHM optical bandwidth of 7 nm and about 8% of the average peak responsivity of 163 A/W at 10 /spl mu/W optical input.
