Abstract :

In this paper, an optical filter based on a two dimensional photonic crystal
ring resonator (PCRR) with triangular lattice is designed and presented. For this
purpose, the effects of positioning, arrangement and the number of the inner rods of the
dual-curved PCRR on the performance characteristics of our optical filter such as the
transmission coefficient and the quality factor have been fully investigated. Calculation
results show that a transmission coefficient of 100% with a quality factor of 2400 at the
operating wavelength of nearly 1576 nm can be achieved. The proposed optical filter
comparatively performs better than the previously reported ones. In addition, this
structure can be used for the design of optical multi-channel demultiplexer. To study the
photonic band gap of our structure, the plane wave expansion (PWE) method has been
used and the finite-difference time-domain (FDTD) method has also been employed to
analyze the optical behavior of the proposed device.
