Erbium-doped and Raman microlasers on a silicon chip fabricated by the sol–gel process [PDF]

open access: yes, 2005
We report high-Q sol–gel microresonators on silicon chips, fabricated directly from a sol–gel layer deposited onto a silicon substrate. Quality factors as high as 2.5×10^7 at 1561 nm were obtained in toroidal microcavities formed of silica sol–gel ...
