Abstract

We investigate the reconfigurable resonator based on five times self-coupled photonic waveguide for versatile functionalities. These include a high-performance notch filter, bandpass filters of Bessel and Chebyshev types with improved shape factors, extinction ratio (ER) of more than 40 dB, high Q-factors, tunable ultra-high sharp Fano resonances with slope rates exceeding 1000 dB/nm and high ERs, the optical analog of multi-band electromagnetically induced transparencies, and tunable true-time delay lines with a considerable delay range.
