Low Loss and High-Quality Factor Optical Filter Using Photonic Crystal-Based Resonant Cavity

Abstract

Abstract Transmission efficiency and quality factor are two of the most crucial characteristics in designing optical band pass filters. In this paper, we proposed a novel structure for realizing an optical filter. For the wavelength selecting part of the filter, we employed a V-shaped resonant cavity. The obtained filter has a resonant mode at 1313 nm with transmission efficiency and quality factor as much as 97 % and 3548, respectively.
