Abstract

AbstractIn this paper, we propose a heterostructure multichannel add/drop filter based on 2-D photonic crystal ring-resonator in which, add and drop operations are accomplished by coupling between two W1 waveguides. The wavelength spacing of 10.3 nm, as well as the average cross-talk of â37.5 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 filterâs cross-talk has an average of â40 dB. Simulations are performed using 2-D finite-difference time-domain calculations.
