Built-in Microplanar Lens for Light Coupling to Two-Dimensional Photonic Crystal Waveguide

摘要

We propose a built-in planar lens for coupling light to a waveguide on a 2-D photonic crystal (PhC) membrane. A 2-D PhC wave guide with the built-in lens has been fabricated with AlGaAs. Improvement in coupling performance is discussed in comparison to waveguides with straight ends as cleaved.
