主　　题：microfiber knot resonator graphene heater thermo-optical modulation 

摘      要：Efficiently tuning the output intensity of an optical device is of vital importance for the establishment of optical interconnects and ***-optical modulation is an easily implemented and convenient approach and has been widely employed in photonic *** this paper,we proposed a novel thermo-optical modulator based on a microfiber knot resonator(MKR)and graphene *** applying voltage to graphene,the resonant property of the MKR could be thermally tuned with a maximum phase shift of 2.1π.Intensity modulation shows a fast optical response time thanks to the high thermal conductivity of graphene and the thin microfiber diameter of the MKR.
