INTRINSIC FIBER OPTIC INTERFEROMETER BASED ON PHOTOINDUCED FRESNEL REFLECTORS
光激菲涅耳反射器形成的本征光纤干涉仪

Large,photoinduced Fresnel reflectors are obtained when the hydrogen-loaded,CeO2-doped optical fiber ig exposed to a single focused 248nm laser beam. Baged on this kind of reflectors.the intrinsic two beam interferometers were formed. Temperature sensitivity of this interferometer is demonstrated by experiment.
