Abstract

A new type of absolute cryogenic radiometer has been fabricated at the microscale level for direct substitution optical fiber power measurements. It consists of three parts: an absorber, electrical heater, and thermometer all on a single micro-machined membrane. The device has been shown to be sensitive to power levels down to 1 pW.
