Fabrication methods of optical resonant filters with a close-to-rectangle filtering profile.
The potential applications of optical resonant filters for optical communication systems can be significant. Three approaches to achieve a close-to-rectangle filtering profile for optical resonant filter were investigated and proven experimentally. The combination of the filtering sharpness, which comes from the resonance nature, and a flattened filtering window realized the close-to-rectangle filtering profile that can enhance the bandwidth efficiency.
