Coherent control of photon transmission : slowing light in coupled resonator waveguide doped with $\Lambda $ Atoms

open access: yes, 2007
In this paper, we propose and study a hybrid mechanism for coherent transmission of photons in the coupled resonator optical waveguide (CROW) by incorporating the electromagnetically induced transparency (EIT) effect into the controllable band gap ...

Structural Dependence of Group Velocity and Leakage Loss in 1-D Photonic Crystal Coupled Resonator Optical Waveguide With Modulated Mode-Gap

open access: yesIEEE Photonics Journal, 2012
One-dimensional photonic crystal coupled resonator optical waveguide (1-D PC-CROW) based on mode-gap confinement has a possibility to reduce leakage losses compared with conventional 1-D PC-CROW constructed by placing defects periodically.
