This theoretical study investigates the influences of thermal and optomechanical effects on the formation of optical frequency comb (OFC) in whispering gallery-mode (WGM) microcavities. The results show that the thermal effects cause a redshift in the cutoff order and center frequency of OFC, which can be tuned by varying the power and detuning of the pump field.
We present a theoretical study that combines thermal and optomechanical effects to investigate their influences on the formation of the optical frequency comb (OFC) in whispering gallery-mode (WGM) microcavities. The results show that the cut-off order and center frequency of OFC affected by thermal effects exhibit an overall redshift by varying the power and detuning of the pump field, which provides the possibility of tuning the offset frequency of OFC. Our study demonstrates a method to characterize the effect on the generation of OFC and the tuning of its offset frequency in a WGM resonator with opto-thermo-mechanical properties and pave the way for the future development of OFC in thermo-optomechanical environments.& COPY; 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
