1. An optical whispering gallery mode resonator device, comprising:
- a substrate having a top surface and a bottom surface parallel to the top surface; and
an optical material located on the top surface of the substrate and engaged to the substrate, wherein the optical material is different from a material of the substrate and the substrate and the optical material are shaped to collectively form a conical shape in which side surfaces of the substrate and the optical material are flat surfaces and form an angle with respect to the top and bottom surfaces of the substrate, wherein the conical shaped optical material is structured as an optical resonator supporting one or more optical whispering gallery modes circulating around a symmetric axis of the conical shape.

9. A method for fabricating an optical whispering gallery mode resonator device, comprising:
-
providing a substrate having a top surface and a bottom surface parallel to the top surface; engaging an optical material on the top surface of the substrate, wherein the optical material is different from a material of the substrate; and shaping the engaged substrate and the optical material together to form a conical shape in the engaged substrate and the optical material to make the conical shaped optical material an optical resonator supporting one or more optical whispering gallery modes circulating around a symmetric axis of the conical shape. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
