Thermal tunable silicon valley photonic crystal ring resonators at the telecommunication wavelength.Tunable ring resonators are essential devices in integrated circuits.  Here we theoretically demonstrate the first tunable VPC ring resonator in the telecommunication wavelength region, the resonance peaks of which are tuned by controlling the temperature based on the thermal-optic effect of silicon.  Since thermal tuning has been broadly applied in silicon photonics, our design can be readily applied in integrated photonic circuits and will find broad applications.  Furthermore, our work opens new possibilities and deepens the understanding of designing novel tunable VPC photonic devices.
