Simulations of Coupled Photonic Crystals Waveguides Constructed with a Portion of 12-Fold Photonic Quasicrystals

Abstract

Two-dimensional coupled photonic crystals waveguides (CPCWs) constructed with a portion of 12-fold photonic quasicrystals are studied. Finite-difference time-domain is performed to investigate the properties of light propagating through the waveguides, and shows that reduced group velocity and flexible waveguide modes can be obtained in such CPCW structures. Our results verify a feasible way for constructing wavelength filter, demultiplexer, etc. multichannel operations for photonic integrated circuits.
