AbstractThis SBIR technology transfer program offers the opportunity to produce a new generation of advanced large area and monolithic pryoelectric detector arrays that fully exploit the benefits of domain engineering and "smart-cut" technologies. SRICO will Investigate domain-engineering patterns to reduce acoustic noise as well as techniques to optimize a thin film absorber to enhance the detector absorptivity without substantially increasing thermal mass. Also, a method to extend domain engineering to create monolithic broadband position sensors and arrays will be explored. Smart-cut transfer of domain patterned crystal films on order of a few microns thick to silicon would enable formation of uniform large area pyroelectric detector arrays that are at the same time ten times more sensitive than state of the art sensors. The proposed domain engineered thin film platform would enable the production of new, high performance pyroelectric detectors, power meters, energy meters, broadband radiometers, custom OEM detectors, and multi-element imaging sensors.
