Intracavity Fiber Sensors Are Sensitive and Inexpensive

Breck Hitz

A novel approach to monitoring fiber optic sensors by placing them inside a mode-locked laser resonator has been conceived and demonstrated by researchers at Insensys Ltd. of Fareham and at Aston University, both in the UK. The technique is sensitive, and its straightforward design eliminates several expensive components required in other fiber optic monitoring systems. Figure 1. In wavelength division multiplexing, each sensor reflects a different wavelength. The sensors can be fiber Bragg gratings, Fabry-Perot interferometers or other interferometric devices whose reflective spectrum...Read full article
