Inverse Design of Photonic Devices with Strict Foundry Fabrication Constraints

نویسندگان

چکیده

We introduce a new method for inverse design of nanophotonic devices which guarantees that resulting designs satisfy strict length scale constraints - including minimum width and spacing required by commercial semiconductor foundries. The adopts several concepts from machine learning to transform the problem topology optimization with an unconstrained stochastic gradient problem. Specifically, we conditional generator feasible adopt straight-through estimator backpropagation gradients latent design. demonstrate performance reliability our designing common integrated photonic components.

Silicon-based Photonic Devices: Design, Fabrication and Characterization

The field of Information and Communication Technologies is witnessing a development speed unprecedented in history. Moore’s law proves that the processor speed and memory size are roughly doubling each 18 months, which is expected to continue in the next decade. If photonics is going to play a substantial role in the ICT market, it will have to follow the same dynamics. There are mainly two gro...

Fabrication of Integrated Graphene Photonic Devices

Graphene is a single-atom-thick layer of carbon atoms in a honeycomb lattice. It is currently a popular material for study in condensed matter physics and related fields [1-6]. The material has a large number of proposed potential applications including integrated photonic devices. Saturable absorption and photocurrent generation has already been successfully demonstrated [1,2]. We aim to study...

Design of photonic crystal devices

The subject of this PhD thesis is the study of photonic crystal waveguides that incorporate discontinuities or structural fabrication-induced variations. For the numerical study of these devices the mode matching (MM) method is proposed. The comparison of the MM method with the couple mode theory (CMT) showed that the CMT can provide only a first approximation to the perturbation-induced scatte...
