High Efficiency Nonuniform Grating Coupler by Utilizing the Lag Effect in the Dry Etching Process
Integrated optics devices Gratings
2015/6/10
Utilizing the lag effect in dry etching, a nonuniform silicon-on-insulator grating coupler is designed and fabricated. Over 80% (>-1dB) coupling efficiency is theoretically obtained and experimental c...
Fully-Etched Photonic Crystal Grating Coupler as an Interface between Single-Mode Fibers and Photonic Circuits on Silicon-on-Insulator
Integrated optics devices Photonic crystals
2015/6/10
A fully-etched photonic crystal grating coupler with low back reflections is introduced as an interface between single-mode fibers and silicon-on-insulator wire waveguides. Peak coupling efficiency of...
Bragg’s grating coupler in planar optical sol-gel waveguides
integrated optics planar waveguides grating coupler sol-gel method
2011/4/26
The aim of our investigation was to develop a technique of producing Bragg’s grating couplers on planar waveguides obtained by means of the sol-gel technique. Introducting a light beam into the wavegu...
