Abstract
Example methods, devices, and systems for optical emission are disclosed. An example device can comprise one or more optical filters. The one or more optical filters can be configured to be coupled to an optical amplifier. The device can comprise a microresonator configured to receive an output of the one or more optical filters and output, based on parametric multiwave mixing, a frequency comb. The one or more optical filters and the microresonator can be integrated into a single chip.
Claims8
A device, comprising:
- a first portion comprising an optical amplifier and a transmissive end;
- and
- a second portion adjacent the transmissive end of the first portion and configured to receive an output from the optical amplifier, wherein the second portion comprises:
- one or more tunable optical filters;
- and
- a microresonator configured to:
- receive an output of the one or more tunable optical filters,
- reflect light back to the one or more tunable optical filters, and
- output, based on parametric multiwave mixing, a frequency comb,
- wherein the frequency comb comprises a soliton-modelocked comb generated simultaneously with injection locking.
