Nanocavity Confinement by Orthogonal Valley- and SSH- Topological Interfaces In Glide-Symmetric Photonic Crystal Structures
Takahiro Uemura, Wei Dai, Yuto Moritake +3
Valley photonic crystals enable valley-dependent transport and chirality-selective emission, but incorporating wavelength-scale localization remains challenging. Existing valley-ph…
Inverse-Designed High-Q/V Silicon Nitride Photonic Crystal Cavities for Second- and Third-Harmonic Generation
M. Takiguchi, P. Heidt, X. Z. Lim +7
SiN photonic crystal (PhC) cavities are promising platforms for nonlinear and quantum photonics because of their wide transparency window, CMOS compatibility, and negligible two-ph…
Low loss switchable topological photonic crystal enabled by submicron-scale patterning and phase-change of Sb2Se3
Takahiro Uemura, Yuto Moritake, Eiichi Kuramochi +3
Photonic topological insulators (PTIs) offer robust platforms for light manipulation, but reconfigurable control of their topological properties without degrading performance remai…
Photonic topological phase transition induced by material phase transition
Takahiro Uemura, Yuto Moritake, Taiki Yoda +5
Photonic topological insulators (PTIs) have been proposed as an analogy to topological insulators in electronic systems. In particular, two-dimensional PTIs have gained attention f…
High Transmission in 120-degree Sharp Bends of Inversion-symmetric and Inversion-asymmetric Photonic Crystal Waveguides
Wei Dai, Taiki Yoda, Yuto Moritake +3
Bending loss is one of the serious problems for constructing nanophotonic integrated circuits. Recently, many works reported that valley photonic crystals (VPhCs) enable significan…
Ultrafast and energy-efficient all-optical switching with graphene-loaded deep-subwavelength plasmonic waveguides
Masaaki Ono, Masanori Hata, Masato Tsunekawa +4
All-optical switches have attracted attention because they can potentially overcome the speed limitation of electric switches. However, ultrafast, energy-efficient all-optical swit…
All-optical dynamic modulation of spontaneous emission rate in hybrid optomechanical cavity quantum electrodynamics systems
Feng Tian, Hisashi Sumikura, Eiichi Kuramochi +4
Recent nanofabrication technologies have miniaturized optical and mechanical resonators, and have led to a variety of novel optomechanical systems in which optical and mechanical m…
