Blue band nonlinear optics and photodarkening in silica microdevices
文献摘要：
There are extensive studies to date on optical nonlinearities in microcavities at the near and mid-IR wavelengths.Pushing this research into the visible region is equally valuable.Here,we demonstrate a directly pumped,blue band Kerr frequency comb and stimulated Raman scattering(SRS)at 462 nm in a silica nanofiber-coupled whis-pering gallery microcavity system.Notably,due to the high optical intensities achieved,photodarkening is unavoidable and can quickly degrade the optical quality of both the coupling optical nanofiber and the micro-cavity,even at very low pump powers.Nonetheless,stable hyperparametric oscillation and SRS are demonstrated in the presence of photodarkening by taking advantage of in-situ thermal bleaching.This work highlights the challenges of silica-based,short wavelength nonlinear optics in high-quality,small mode volume devices and gives an effective method to overcome this apparent limitation,thus providing a baseline for optics research in the blue region for any optical devices fabricated from silica.
