Abstract

An optical filter is disclosed which uses an integral GT resonator and fiber coupler to form a Michelson interferometer. The coupler will divide the light into two arms, with one arm being reflected by a high reflectance mirror, and the other arm being reflected by a GT resonator. The size of the arms and the spacing of the resonator determines the filtering characteristics of the filter. Tuning the filter is accomplished by illuminating a photosensitive fiber material that is used to form a portion of the filter. Illumination causes the refractive index of the material to change, and thereby changes the effective length of the fiber, which in turn adjusts or tunes the characteristics of the filter.
