Abstract
A method of forming an attenuator on an optical device includes forming a ridge for a waveguide. The ridge is formed in a light-transmitting medium that is positioned on a base. The ridge extends upwards from slab regions of the light-transmitting medium. The method also includes forming trenches in the slab regions of the light-transmitting medium such that the trenches extend through the light-transmitting medium to the base. The trenches are formed such that the ridge is located between the trenches. The method also includes forming a semiconductor in a bottom of each of the trenches and then doping a region of each of the semiconductors.
