Abstract

Micro-ring cavity on glass fibers and molybdenum wires were fabricated. The cavities were Rh B doped organic-inorganic hybrid sol-gel films. Cavity quality factor (Q value) as high as 5880 was obtained, which proves that organic-inorganic matrix are excellent materials for micro-cavity fabrication. For large cavity diameter (D=140 μm), we observed clear whispering gallery modes that belongs to the same series. On the other hand, when cavity diameter reduced to 50 μm, higher order whispering gallery modes also appeared.
