Review of femtosecond infrared laser‐induced fibre Bragg grating sensors made with a phase mask

Abstract

Purpose

The purpose of this paper is to present a review of research performed at the Communications Research Centre Canada on sensing applications of femtosecond infrared laser‐inscribed Bragg gratings.

Design/methodology/approach

By using fibre Bragg gratings induced with ultrafast infrared radiation, inscription of high temperature stable sensors in standard and exotic optical waveguides is investigated for a variety of novel applications.

Findings

Generally, femtosecond laser‐induced gratings are effective sensors that can be applied in situations and environments where most fibre optic sensors are not effective.

Originality/value

The paper is a review of existing work already published in the literature and provides an overview of this technology to the reader.
