Abstract

Claims (38)

1. A photonics integrated chip comprising:

a plurality of light source banks;

a combiner; and

a detector array; wherein:

each light source bank of the plurality of light source banks comprises:

a set of light sources;

a first optical trace connected to the combiner;

a second optical trace connected to the detector array; and

a crossing at which the first trace of the light source bank crosses the second trace.

2. The photonics integrated chip of claim 1 , wherein:

the combiner combines inputs received from the first optical traces of the plurality of light source banks and outputs a combined signal.

3. The photonics integrated chip of claim 2 , comprising a splitter positioned to receive the combined signal and configured to split the combined signal into a plurality of signals.

4. The photonics integrated chip of claim 3 , comprising a plurality of emission regions from which the plurality of signals exit the photonic integrated chip.

5. The photonics integrated chip of claim 4 , wherein:

the plurality of emission regions comprises a plurality of outcouplers.

a controller that receives detector signals from the detector array and monitors and controls a frequency of light emitted the plurality of emission regions.

7. The photonics integrated chip of claim 1 , wherein:

each light source bank of the plurality of light source banks comprises a third optical trace connected to the detector array.

8. The photonics integrated chip of claim 7 , wherein:

each light source bank of the plurality of light source banks comprises a photonic component that is configured to receive signals from the set of light sources and to output a corresponding signal output to each of the first, second, and third trace of the light source bank.

9. The photonics integrated chip of claim 8 , wherein:

the photonic component is an arrayed waveguide grating.

10. A photonics integrated chip comprising:

a plurality of light source banks;

a combiner; and

a detector array; wherein:

each light source bank of the plurality of light source banks comprises:

a plurality of light sources;

a first optical trace connected to the combiner;

a second optical trace connected to the detector array; and

a multiplexer that connects the plurality of light sources to each of the first optical trace and the second optical trace.

11. The photonics integrated chip of claim 10 , wherein:

the combiner combines inputs received from the first optical traces of the plurality of light source banks and outputs a combined signal.

12. The photonics integrated chip of claim 11 , comprising a splitter positioned to receive the combined signal and configured to split the combined signal into a plurality of signals.

13. The photonics integrated chip of claim 12 , comprising a plurality of emission regions from which the plurality of signals exit the photonic integrated chip.

14. The photonics integrated chip of claim 13 , wherein:

the plurality of emission regions comprises a plurality of outcouplers.
