Improved dual grating-assisted directional coupler for silicon nanophotonics

Improved dual grating-assisted directional coupler for silicon nanophotonics
Improved dual grating-assisted directional coupler for silicon nanophotonics
In this paper we present preliminary experimental results of an improved dual grating-assisted directional coupler. As the top SiON layer is thicker, the total insertion loss is reduced, and coupling efficiency significantly increased in the L-band wavelength region, compared to the previously reported results. The coupling efficiency is in the 42-56% range for both C-and L-band wavelength regions. Temperature dependence of the coupler has been also investigated.

Abstract

In this paper we present preliminary experimental results of an improved dual grating-assisted directional coupler. As the top SiON layer is thicker, the total insertion loss is reduced, and coupling efficiency significantly increased in the L-band wavelength region, compared to the previously reported results. The coupling efficiency is in the 42-56% range for both C-and L-band wavelength regions. Temperature dependence of the coupler has been also investigated.
