Abstract: The present disclosure provides an optical detector for detecting radiation. The optical detector includes an optical light guide that incorporates a sensing region. The sensing region includes a sensing material that emits luminescence light when the sensing material is exposed to suitable ionizing radiation and accrues trapped charge which is released and produces optically stimulated luminescence (OSL) when the sensing material is optically stimulated. The optical detector also includes a light source for optically stimulating the sensing material and a light detector for detecting the OSL. The optical light guide is arranged to guide light through the sensing region and between the sensing region and the luminescence light detector.

Abstract: A photonic link system for transmitting and receiving an optical signal in accordance with an input signal is disclosed. The system includes a photonic transmitter and a photonic receiver. The photonic transmitter includes a first signal path including a first photonic modulator for producing a first output optical signal modulated by the input signal and a second signal path in parallel with the first path photonic path where the second signal path also includes a second modulator for producing a second output optical signal modulated by the input signal. The relative gain of the first and second signal paths is different to provide first and second output optical signals of different relative gain. The photonic receiver includes a first input to receive the first output optical signal from the photonic transmitter and a second input to receive the second output optical signal from the photonic transmitter. The photonic receiver further includes a switch for selectively switching between the first and second inputs in accordance with a measure of magnitude of one or both of the first and second input optical signals.
