Low Power Optical Phase Array Using Graphene on Silicon Photonics

Abstract

In this report, Columbia University investigated the potential of using low loss and low power graphene phase shifter for integrated silicon photonics. The work developed the critical steps for a platform consisting of 2D materials embedded in waveguides, in which electrostatic doping is used for tuning the dielectric properties of the guiding structures. Graphene as well as other 2D materials and thin films, have been shown recently to exhibit high tunability of index with doping.This platform could enable ultrafast devices with unprecedented low power.
