Abstract
The optical device includes a plurality of waveguides and an optical grating. A first portion of the waveguides act as input waveguide configured to carry a light beam that includes multiple light signals to the optical grating. The optical grating is configured to demultiplex the light signals. A second portion of the waveguides act as output waveguides configured to carry the demultiplexed light signals away from the optical grating. A method of forming the optical device includes sequentially forming the waveguides and the optical grating while a single mask defines the location of the waveguides and the optical grating.
