Ultra-compact photonic crystal waveguide spatial mode converter and its connection to the optical diode effect
Integrated optics devices Guided waves
2015/8/7
We design an extremely compact photonic crystal waveguide spatial mode converter which converts the fundamental even mode to the higher order odd mode with nearly 100% efficiency. We adapt a pre...
Topology-Optimized Slow-Light Couplers for Ring-Shaped Photonic Crystal Waveguide
Integrated optics devices Photonic crystals Waveguides planar
2015/6/4
We demonstrate a topology-optimized coupler for a ring-shaped photonic crystal waveguide to improve the coupling of light located in the slow-light regime. An enhancement of the coupling efficiency of...
Photonic Crystal Waveguide Weakly Interacting with Multiple Off-Channel Resonant Features Formed of Kerr Nonlinear Dielectric Media
Kerr Nonlinear Dielectric Media Resonant Features
2008/10/29
A theoretical study is presented of guided modes of a photonic crystal waveguide for cases in which they interact with multiple bound electromagnetic modes localized on off-channel impurity features o...
Wannier Basis Design and Optimization of a Photonic Crystal Waveguide Crossing
Design optimization photonic crystal (PC) devices
2015/8/11
We employ a novel platform for the realization of tunable photonic crystal (PC) circuits together with a Wannier basis modeling and optimization scheme in order to design a broad-band waveguide crossi...
