Abstract :
We demonstrated that silicon (Si) microsphere resonators, which exhibited high quality factor (Q) whispering-gallery-modes (WGMs), could be rapidly fabricated from Si-cored fibers using CO2 laser reformation. WGMs were excited using the tapered silica fiber coupling technique, and a record resonant Q as high as 4 × 105 was obtained from a Si microsphere with a diameter of 25.4 μm. The shift of resonant wavelength caused by thermooptic effect of Si material was also observed.
