Near-infrared wavelength tuning of monolayer graphene on Silicon Nitride waveguides.

In this work, we detail the integration of monolayer graphene electrodes in Silicon Nitride waveguides to achieve wavelength tuning. The numerical results show that wavelength shifts of a few hundred to several thousand picometers shift can be obtained depending on the configuration. These results will help guide the design of graphene-based tunable optical devices operating in the near infrared range. [ABSTRACT FROM AUTHOR]
