Abstract	:	A new structure to utilize intersubband absorption based on GaAs InversionChannel technology is proposed. A GaAs CCD structure enables a two dimensionalinfrared imager. The existing QWIP technology utilizes a series of about 40 quantumwells with the dark current determined by therrnionic current over the quantum wellbarrier. The proposed new structure has one or two quantum wells with dark currentlimited by the recombination current in the AlGaAs barrier layers. A grating structure asan illumination coupler may be incorporated into the device fabrication sequence toenable the detection of normally incident light. It has been shown that the couplingefficiency maximum occurred when it satisfied the second order Bragg difhction.....-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
