Abstract

We design and fabricate a new taper structure for adiabatic mode transformation in two-dimensional photonic-crystal waveguides patterned into a GaInAsP confining layer. The taper efficiency is validated by measurement of a reduction of the reflection between an access ridge and a photonic-crystal guide with one missing row from 6% to less than 1%. This taper is then incorporated into a 60° bend; simulations demonstrate a 90% transmission between multimode ports.

  16. The peak transmission is 95%. The less-than-100% transmission is probably due to the mismatch between the rectangular Finite-difference time-domain mesh and the sixfold symmetry of the PC lattice. The two sections of the PCW are not equivalent in the numerical simulation.
