All-Optical Control of Ultrahigh-Q Whispering Gallery Microspheres with Laser-Induced Graphene
We present a method for all-optical control of silica whispering-gallery-mode microspheres with laser-induced graphene (LIG). Polyimide (PI) films are carbonized to LIG under CO2 laser irradiation. A 980 nm laser is used as a pump light to irradiate the LIG surface, and the transmission and reflection spectra of microcavities are studied. Experimental results show that the tuning scheme maintains a Q factor of approximately
