Abstract

A fast FBG sensor interrogator based on a SOI ring resonator (RR) filter is presented. The measurement of the Bragg wavelength shift is based on the detection of the signals at the output ports of the RR. Ring resonance wavelength is tuned and fixed by an integrated heater and the ring acts as a passband filter for the reflected FBG spectrum.
