Abstract
A digital optical switch using a velocity coupler tapered both in dimension and in index, which shows the smallest voltage-length product reported so far for digital optical switches, is presented. Numerical results for the graded-index channel waveguide coupler, which can be applied to all z-variant structures with 2D graded-index profile, are presented.<>
