Circular-lattice photonic crystal Taper for optical waveguides
Last modified: 2012-01-02
Abstract
A new taper to coupling two ridge waveguides with different width dimensions by means of a circular-lattice photonic crystal has been theoretically investigated. The studies were carried out by using a finite-difference time-domain (FDTD) method. Coupling efficiency above 65 % was obtained for waveguides whose widths were related by a factor of five.
