All-optical switch with two periodically curved nonlinear waveguides [PDF]
Optics Letters, 35(3) 321-323(2010), 2008 We propose a type of all-optical switch which consists of two periodically curved nonlinear optical waveguides placed in parallel. Compared to the all-optical switch based on the traditional nonlinear directional coupler with straight waveguides, this all-optical switch has much lower switching threshold power and sharper switching width.

Frontiers in Cell and Developmental Biology, 2023 Astonishing functional diversity exists among arthropod eyes, yet eye development relies on deeply conserved genes. This phenomenon is best understood for early events, whereas fewer investigations have focused on the influence of later transcriptional ...

Atom optics with microfabricated optical elements [PDF]
Conference Digest. 2000 International Quantum Electronics Conference (Cat. No.00TH8504), 2000 We introduce a new direction in the field of atom optics, atom interferometry, and neutral-atom quantum information processing. It is based on the use of microfabricated optical elements. With these elements versatile and integrated atom optical devices can be created in a compact fashion.

Optical Response of Chiral Multifold Semimetal PdGa
Crystals, 2021 We present a theoretical study of the band structure and optical conductivity for the chiral multifold semimetal PdGa. We identify several characteristic features in the optical conductivity and provide their origins within the band structure.
