Abstract

A resonant pyroelectric detector was demonstrated to support narrowband and tunable photopyroelectric effect in the near-infrared region. The narrowband pyroelectric device was built on a chalcogenide-metal-fluoropolymer (As2S3-Ag-PVDF) nanograting membrane, which was fabricated inexpensively using a solvent-assisted imprint lithography process. Under the resonant condition, the device exhibited a responsivity of 1.36 V/W. The device’s absorption and pyroelectric characteristics can be tuned using a bias voltage applied to the membrane.
