Tunable erbium-doped microbubble laser fabricated by sol-gel coating
Yong Yang, Fuchuan Lei, Sho Kasumie +4
In this work, we show that the application of a sol-gel coating renders a microbubble whispering gallery resonator into an active device. During the fabrication of the resonator, a…
Raman lasing and Fano lineshapes in a packaged fiber-coupled whispering-gallerymode microresonator
Guangming Zhao, Şahin Kaya Özdemir, Tao Wang +3
We report Raman lasing and the optical analog of electromagnetically-induced-transparency (EIT) in a whispering-gallerymode (WGM) microtoroid resonator embedded in a low refractive…
Controllable optical response by modifying the gain and loss of a mechanical resonator and cavity mode in an optomechanical system
Yu-Long Liu, Rebing Wu, Jing Zhang +4
We theoretically study a strongly-driven optomechanical system which consists of a passive optical cavity and an active mechanical resonator. When the optomechanical coupling stren…
Observation of optomechanical coupling in a microbottle resonator
Motoki Asano, Yuki Takeuchi, Weijian Chen +5
In this work, we report optomechanical coupling, resolved sidebands and phonon lasing in a solid-core microbottle resonator fabricated on a single mode optical fiber. Mechanical mo…
High-Q silk fibroin whispering gallery microresonator
Linhua Xu, Xuefeng Jiang, Guangming Zhao +5
We have experimentally demonstrated an on-chip all-silk fibroin whispering gallery mode microresonator by using a simple molding and solution-casting technique. The quality factors…
Phone-sized whispering-gallery microresonator sensing system
Xiangyi Xu, Xuefeng Jiang, Guangming Zhao +1
We develop a compact whispering-gallery-mode (WGM) sensing system by integrating multiple components, including a tunable laser, a temperature controller, a function generator, an…
