Abstract

By utilizing the band-selective nature of optically resonant nanoparticles, Tanner Research is developing a room temperature multi-spectral IR detection technology termed Nanobolometer. Because the device physics is not based on photodiode/photoconductive (cooled IR detectors) operation, it does not require cooling. It is also not a heat sensing (Microbolometers) scheme and is capable of multi-spectral detection from NIR to LWIR. A nanobolometer is built on a Si substrate for the entire detection bands (NIR-LWIR), which enables low material and fabrication costs, with an added advantage of being able to integrate UV/Vis detector pixels in the same platform. We present the theory and working principle of Tanner's Nanobolomter technology and report a proof-of-concept demonstration that achieved IR detection at 1.5 μm. Tanner's on-going R&D effort aims to extend the detection bands to MWIR/LWIR.
