Optical Narrow Passband Filter

These drawbacks can be avoided using a FP structure with dielectric mirrors. Dielectric mirrors, when properly designed and fabricated, offer high-performance characteristics (high reflectivity with low absorption losses). When using dielectric layers, at least two different materials with high and low refractive index and alternately deposited are needed to obtain narrow passband optical filters. A structure that comprises an array of 16 FP optical...
