Self-healing fibre grating sensor system using tunable multiport fibre laser scheme for intensity and wavelength division multiplexing

Abstract

A fibre grating sensor system using a tunable multiport fibre laser scheme for intensity and wavelength division multiplexing is proposed. The power ratio (1:2:3) between each output port is used to address the sensing information. The network survivability is also considered. This fibre grating sensor system can enhance the sensing capacity and reliability.
