Abstract
An arrayed waveguide grating device includes an input coupler configured to receive a light signal and split the light signal into a plurality of output light signals. The device also includes a plurality of waveguides optically connected to the input coupler, each waveguide having a plurality of waveguide portions having respective sensitivities to variance in one or more parameters associated with operating of the optical arrayed grating device. Lengths of the respective portions are determined such that each waveguide applies a respective phase shift to the output light signal that propagates through the waveguide and the plurality of waveguides have at least substantially same change in phase shift with respective changes in the one or more parameters associated with operation of the device. An output coupler is optically connected to the plurality of waveguides to map respective light signals output from the plurality of waveguides to respective focal positions.
