| Abstract |
In this paper we have proposed a photonic crystal structure to enhance the coupling
efficiency between photonic crystal waveguide (PCW) and the conventional dielectric waveguide.
The proposed waveguide characterized with employing the taper structure and varying the holes’
radius in the taper. Two-dimensional (2D) finite-difference time-domain (FDTD) method has been
used to analyze the structure. The simulation results show that the coupling efficiency can be
achieved as high as 81.6% at the wavelength of 1.55um. |
