  • Abstract
    A new sensor for detecting surface acoustic waves (SAWs) is presented. The system uses single-mode optical fibres throughout, and requires only one 3 dB directional coupler. The sensor is tunable to acoustic frequencies above 8 MHz. The new system can be realised in a particularly compact form, and could form the basis of a miniature instrument.
