Photothermal effects in passive fiber Bragg grating resonators

Chow, Jong H.; Sheard, Benjamin S.; McClelland, David E.; Gray, Malcolm B.; Littler, Ian C. M.


Photothermal effects in passive Fabry–Perot resonators are caused by the conversion of circulating optical energy into heat as a result of absorption. This results in thermal change in the resonator’s optical path length, the round-trip phase, and hence the resonance condition. We describe a simplified dynamic numerical model for photothermal effects in passive fiber Bragg grating resonators and present results of their experimental observation.
