Abstract

A photonic sensing system includes an interrogator coupled to a sensing fiber. The interrogator includes a light source (44) configured to emit light, and a photonic integrated circuit (48) comprising a plurality of photonic components like polarisation rotatot (58), circulator (64), splitter (68), edge coupler (62, 40), waveguides (66, 70, 72) and photodiodes (74, 80, 82). The PIC is configured to transmit the light emitted by the light source and to receive reflected light from the sensing fiber. The interrogator also includes a plurality of integrated circuit (86, 88, 90, 92, 94, 96) components configured to process and analyze signals from the interrogator to determine one or more measurands like current flowing through an electrical conductor around which the sensing fibre is coiled.
