Claims

C1strongest claim

Our device, utilizing a superconducting microwave cavity, generating the frequency comb via cavity phase modulation enabled by the field-induced effective χ(2) of SrTiO3.

C2weakest assumption

That the Pockels-like effect and field-induced effective second-order nonlinearity in the quantum paraelectric phase of SrTiO3 are sufficient to produce a usable frequency comb at cryogenic temperatures with low electrical power and without additional optical components.

C3one line summary

An on-chip cryogenic microwave frequency comb is produced via electric-field-induced phase modulation in quantum paraelectric SrTiO3 inside a superconducting resonator.
