Paper Abstract

In this paper, we propose and demonstrate an all-optical switch using graphene oxide infiltrated subwavelength grating waveguide. Benefiting from the extremely large Kerr coefficient of graphene oxide (four orders of magnitude larger than conventional materials) and large mode volume overlap factor of the subwavelength grating waveguide (4~10 times larger than conventional strip waveguides), the switch is capable of achieving THz speed with less than 1 fJ energy consumption per bit, which is more than three orders of magnitude smaller than THz switches reported so far.
