Abstract
We review the whispering gallery type microtoroid resonator fabricated on a silicon chip. Using this structure, an Erbium doped silica green laser through three-photon-absorption process is demonstrated and an on-chip Raman laser operating at single mode with fundamental linewidth as low as 3-Hz is reported.
