Abstract
We present the concept of a dual mode cryogenic detector, utilising a predictable quantum efficient silicon photodiode, and demonstrate the behaviour of the detector from room temperature down to 30K. The detector absorbs visible radiation generating either heat or photo-current, dependent on the selected mode of operation. In effect this detector links optical power to fundamental constants through two different routes in one artefact. Forward biasing is used in lieu of resistive heating to provide the electrical substitution power. This in itself is a novel idea.Citation
