Abstract
A process for forming a mode size converter with an out-of-plane taper formed during deposition with a shadow mask is disclosed. Mode-size converters according to the present invention can have any number of configurations. Measured coupling efficiencies for waveguides with mode size converters according to the present invention show marked improvement.
