Enhanced Kerr Optical Nonlinearity of Waveguides Integrated with Graphene Oxide

摘要

We experimentally demonstrate enhanced optical Kerr nonlinearity of hybrid integrated waveguides coated with graphene oxide (GO). Owing to the high Kerr nonlinearity of GO and strong mode overlap between GO and waveguide, up to ∼9.5-dB enhancement of four wave mixing (FWM) conversion efficiency is achieved.
