Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a low-power thermo-optical bistability in a graphene oxide-on-silicon micro-ring resonator which not only retains its high quality factor of 56000 but also exhibits a hysteresis loop for a pump power of only 115-μW.
