Abstract

A novel coupled-cavity waveguide based on two-dimensional triangular lattice photonic crystals was proposed. This structure was composed of the line-defect waveguides

resonant micro- cavity

and ellipse-holes which are located between line-defect waveguide and resonant micro-cavity. The band structure of line-defect waveguide was simulated by the method of the plane-wave expansion. The transmission characteristics and quality factor of the coupled-cavity waveguides were investigated by the finite-difference time-domain (FDTD) method. By optimizing the structural parameters such as amount

size

and arrangement of ellipse-holes between the resonant micro-cavity and the line-defect waveguide

a 90% transmission efficiency was obtained with a

-factor of 10

. Then

appropriate parameters were selected

a high

-factor of 10

was achieved

the transmission efficiency corresponding to the resonance frequency was still above 60%.
