Abstract

Fabricating the mode transformer includes forming a cladding trench in a first light-transmitting medium that is included on a wafer. A lateral cladding is formed in the cladding trench such that the lateral cladding becomes an optical cladding on a lateral side of a first tapered portion of a waveguide. A second light-transmitting medium is formed on the wafer such that a portion of the first light-transmitting medium is between a bottom of the trench and the second light-transmitting medium. The second light-transmitting medium is patterned so as to define a second tapered portion of the waveguide over the first tapered portion of the waveguide.
