Broadband, Flat-Top, Silicon Photonic Contra-Directional Couplers Assisted by Asymmetric Multimode Photonic Crystals
Grating-assisted contra-directional couplers (CDCs) as 4-port wavelength-selective devices hold great potential as add-drop filters, multiplexers, routers, etc, for various integrated-optics applications. However, these devices have inherent low coupling strengths due to the coupled modes confined i...
