ABSTRACT:
An optical filter is disclosed. The filter includes a light distribution component having an output side. A plurality of array waveguides are configured to deliver a light signal into the light distribution component such that the light signal is incident on the output side of the light distribution component. The array waveguides are configured to adjust the location where the light signal is incident on the output side.
