- 摘要：
- A nonuniform-shape photonic crystal taper integrated with a
single-mode optical fiber and a photonic crystal waveguide for highefficiency
mode coupling is presented. The curvature of the tapering section
is varied by the parameter α. For values of α set to 2 and 0.5, concave and
convex tapers are obtained, respectively. Numerical calculations yield an
average coupling efficiency greater than 97% at a short taper length of
20.52 μm for the convex-shape taper. Subsequently, the value of the
parameter α is varied for investigating the effects of curvature on coupling
efficiency and compactness of different types of taper.
