Abstract: Optical microresonator platforms are provided comprising a substrate having a surface, a plurality of SiO2 pillars, and a plurality of SiO2 whispering gallery mode (WGM) optical microresonators, each SiO2 pillar extending from the surface of the substrate and terminating in a corresponding SiO2 WGM optical microresonator of the plurality of SiO2 WGM optical microresonators, wherein the substrate, the plurality of SiO2 pillars and the plurality of SiO2 WGM optical microresonators form a monolithic structure, and further wherein the substrate is substantially transparent to visible light. The substrate may be a SiO2 substrate and the SiO2 WGM optical microresonator may be a SiO2 optical microtoroid.
