提出了一种基于激光诱导石墨烯（LIG）的二氧化硅回音壁微球腔全光调谐方法。利用二氧化碳激光器碳化聚酰亚胺（PI）薄膜生成LIG，使用980 nm激光对LIG表面进行光激励，研究了微腔的透射光谱和反射光谱。结果表明：回音壁微腔的品质因子Q值在调谐全过程中保持在108左右，调谐范围约为1.09 nm，灵敏度约为8.8 pm/mW，实现了基于LIG的二氧化硅回音壁微球腔无损Q值的全光调谐。该全光调谐方法具有无机械干扰、保持超高Q值、调谐范围宽等优点，扩展了全光调谐在腔量子动力学、非线性光学、低阈值激光等方面应用。

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 108 throughout the tuning process, with a tuning range and sensitivity of approximately 1.09 nm and approximately 8.8 pm/mW, respectively. This scheme has the advantages of having no mechanical interference, an ultrahigh-Q factor, and a wide tuning range, thus extending all-optical tuning to applications in cavity quantum dynamics, nonlinear optics, and low-threshold lasers.
