Abstract

See full text

An optical modulator includes a waveguide core; a first transition zone located between a first side of the waveguide core and a first electrical contact region; and a second transition zone located between a second side of the waveguide core and a second electrical contact region, wherein one or more of the first transition zone and second transition zone has a variable thickness. The variable thickness is confined to the one or more of the first transition zone and second transition zone. The variable thickness removes a portion of the highly doped first transition zone and the highly doped second transition zone thereby reducing contact resistance.
