The wavelength spacing of 10.3 nm, as well as the average cross-talk of −37.5 dB, are the other features of the proposed filter. Furthermore, nanoscale effects on the filter’s performance including wavelength spacing, cross-talk amount, and dynamic response are considered. By taking into account these effects, the minimum wavelength spacing of 12 nm is obtained, whereas the filter’s cross-talk has an average of −40 dB. Simulations are performed using 2-D finite-difference time-domain calculations.}, number={1}, journal={Journal of Theoretical and Applied Physics}, publisher={OICC Press}, author={Pezeshki, Hamed and Ahmadi, Vahid}, year={2023}, month={Nov.}, keywords={42.79.Sz, 42.82.Et, Heterostructure, Multichannel add/drop filter, Nanoscale effect, Resonator, Ring, Photonic crystal, PACS, 42.70.Qs, 42.79.Ci} }
