Boundary integral equation method for resonances in gradient index cavities designed by conformal transformation optics
Jung-Wan Ryu, Jinhang Cho, Soo-Young Lee +5
In the case of two-dimensional gradient index cavities designed by the conformal transformation optics, we propose a boundary integral equation method for the calculation of resona…
A Novel Analytic Approach to Model Line Edge Roughness using Stochastic Exposure Distribution in Electron-beam Lithography
Rui Guo, Soo-Young Lee
The line edge roughness (LER) becomes a issue of e-beam lithography when feature size is reduced into nanometers. Therefore, minimizing the LER is a important method to increase th…
Exceptional points in coupled dissipative dynamical systems
Jung-Wan Ryu, Woo-Sik Son, Dong-Uk Hwang +2
We study the transient behavior in coupled dissipative dynamical systems based on the linear analysis around the steady state. We find that the transient time is minimized at a spe…
Abnormal high- modes of coupled stadium-shaped microcavities
Jung-Wan Ryu, Soo-Young Lee, Inbo Kim +3
It is well known that the strongly deformed microcavity with fully chaotic ray dynamics cannot support high-Q modes due to its fast chaotic diffusion to the critical line of refrac…
Multi-Valued Logic Gates based on Ballistic Transport in Quantum Point Contacts
M. Seo, C. Hong, S. -Y. Lee +5
Multi-valued logic gates, which can handle quaternary numbers as inputs, are developed by exploiting the ballistic transport properties of quantum point contacts in series. The pri…
Quantum Goos-Hänchen shift and tunneling transmission at a curved step potential
Soo-Young Lee, Jérémy Le Deunff, Muhan Choi +1
We study the quantum Goos-Hänchen (GH) shift and the tunneling transmission at a curved step potential by investigating the time evolution of a wave packet. An initial wave packet…
