Coupled-mode analysis of photonic crystal add-drop filters based on ring resonators
TLDR
In this paper, a two-dimensional photonic crystal add-drop filter based on ring resonators was proposed, which can be applicable to photonic integrated circuits. And the simulation results of this filter obtained from the finite-difference time-domain method are consistent with those from the coupled-mode theory.Abstract:
We propose coupled-mode analysis of a two-dimensional photonic crystal add-drop filter based on ring resonators, which can be applicable to photonic integrated circuits. Mechanism of this proposed add-drop filter is analogous to that of ring resonators resonance, which involves interaction of waveguides and resonators. Simulation results of this filter obtained from the finite-difference time-domain method are consistent with those from the coupled-mode theory. Total transmission up to 99% is verified by both methods.read more
