Si photonic crystal slow-light waveguides optimized through informatics technology

Autor: Keisuke Hirotani, Toshihiko Baba, Ryo Shiratori

Publikováno v: Optics Letters. 46:4422

We modeled the photonic bands of S i O 2 -cladded Si lattice-shifted photonic crystal waveguides via machine learning and found a structure that generates low-dispersion slow light with a group index of approximately 20 in the full C-band at telecom

Optimization of H0 Photonic Crystal Nanocavity using Neural Network

Autor: Ryo Shiratori, Taichi Takeda, Shinichi Shirakawa, Toshihiko Baba, Shota Saito, Ryotaro Abe

Publikováno v: OECC/PSC

We optimized ultrasmall H0 photonic crystal nanocavity using neural network. Record high $Q$ over one million and 280,000 were calculated in air and water, respectively, for 180 nm slab at a wavelength around 1550 nm.

Particle swarm optimization of silicon photonic crystal waveguide transition

Autor: Masaya Nakata, Ryo Shiratori, Toshihiko Baba, Kosuke Hayashi

Publikováno v: Optics Letters. 46:1904

Slow light generated through silicon (Si) photonic crystal waveguides (PCWs) is useful for improving the performance of Si photonic devices. However, the accumulation of coupling loss between a PCW and Si optical wiring waveguides is a problem when s

Optimization of an H0 photonic crystal nanocavity using machine learning

Autor: Shinichi Shirakawa, Ryo Shiratori, Shota Saito, Ryotaro Abe, Taichi Takeda, Toshihiko Baba

Publikováno v: Optics Letters. 45:319

Using machine learning, we optimized an ultrasmall photonic crystal nanocavity to attain a high Q . Training data were collected via finite-difference time-domain simulation for models with randomly shifted holes, and a fully connected neural network
