Abstract
Provided are systems and methods for lithography-free programmable integrated photonics. Various embodiments include a medium having a lithography-free region, and a photonics processor. Under illumination, the medium can exhibit a pumping pattern defining a gain-loss distribution on the lithography-free region, and the photonics processor can modulate the pumping pattern of the lithography-free region by spatially modulating the pumping pattern based on an imaginary-index distribution.
Claims20
A method for photonics processing, comprising:
- receiving at least one optical signal at a medium, wherein the medium comprises a lithography-free region, and wherein the medium optionally comprises a microchip;
- generating a first pumping pattern on the lithography-free region, the first pumping pattern defining a gain-loss distribution;
- spatially modulating the first pumping pattern based on an imaginary-index distribution to generate a second pumping pattern;
- and
- collecting an output from the medium.
A method, comprising:
- receiving at least one optical signal at a medium that comprises a lithography-free region, the medium optionally comprising a microchip;
- illuminating the lithography-free region so as to give rise to a pumping pattern therein that defines a gain-loss distribution on the lithography-free region, the pumping pattern being based at least in part on a target matrix;
- and
- collecting an output from the medium.
An integrated photonics system, comprising:
- a medium comprising a lithography-free region, wherein the medium exhibits, under illumination, a pumping pattern defining a gain-loss distribution on the lithography-free region;
- and
- a photonics processor configured to modulate the pumping pattern of the lithography-free region by spatially modulating the pumping pattern based on an imaginary-index distribution.
