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.
Claims37
A filter, comprising:
- a light distribution component having an output side;
- and
- a plurality of array waveguides 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 being configured to adjust the location where the light signal is incident on the output side.
A filter, comprising:
- a light distribution component having an output side;
- and
- a plurality of array waveguides 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, at least a portion of the array waveguides including effective one or more length tuners, each effective length tuner configured to change the effective length of an array waveguide.
A filter, comprising:
- a light distribution component having an output side;
- a plurality of array waveguides 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;
- and
- an effective length tuner positioned adjacent to a plurality of the array waveguides, the effective length tuner configured to change the effective length of the array waveguides such that the location where the light signal is incident on the output side of the light distribution component changes.
