Abstract
Disclosed are optical devices for coupling radiation between an optical waveguide and an external medium. In one embodiment, an optical device is disclosed comprising a semiconductor die comprising an integrated optical waveguide core and an overlying optical waveguide comprising a waveguide taper and a waveguide facet. The overlying optical waveguide at least partially overlies the integrated optical waveguide core, and the waveguide facet is between about 1 μm and 200 μm from an edge of the semiconductor die. In another embodiment, a method is disclosed comprising providing a substrate comprising an integrated semiconductor waveguide and forming on the substrate an overlying waveguide comprising a waveguide taper and a waveguide facet. The overlying waveguide at least partially overlies the integrated semiconductor waveguide. The method further includes cutting the substrate about 1 μm and 200 μm from the waveguide facet.
