Abstract

A photonic device for splitting optical beams includes an input port configured to receive an input beam having an input power, a power splitter including perturbation segments arranged in a first region and a second region of a guide material having a first refractive index, each segment having a second refractive index, wherein the first region is configured to split the input beam into a first beam and a second beam, wherein and the second region is configured to separately guide the first and second beams, wherein the first refractive index is greater than the second refractive index, and output ports including first and second output ports connected the power splitter to respectively receive and transmit the first and second beams.

Dependent claims

A system for training a device design network, comprising:

an interface configured to input data of a device;
a memory to store the device design network including an encoder, a decoder, and an adversarial block;
and
a processor, in connection with the memory, configured to:
update the encoder and the decoder based on a first loss function to reduce the difference between the input data and output data of the decoder, wherein the encoder is constructed by at least one convolutional layers followed by at least one parallel fully connected layer to extract features of a layout of the device;
and
update the adversarial block to construct by maximizing a second loss function.
