Patent ID: 6965128

Claim:
A microresonator device, comprising: a monocrystalline silicon substrate; an amorphous oxide material in contact with the monocrystalline substrate; a monocrystalline metal oxide selected from the group consisting of alkaline earth metal titanates, alkaline earth metal zirconates, alkaline earth metal hafnates, alkaline earth metal tantalates, alkaline earth metal ruthenates, alkaline earth metal niobates, alkaline earth metal vanadates, alkaline earth metal tin-based perovskites, lanthanum aluminate, lanthanum scandium oxide, gadolinium oxide and mixtures thereof contacting the amorphous oxide material; a first electro-optical waveguide overlying the monocrystalline silicon substrate; a second electro-optical waveguide overlying the monocrystalline silicon substrate; and a first resonator overlying the monocrystalline silicon substrate, said first resonator separated from said first waveguide by a first gap and separated from said second waveguide by a second gap.
