Brillouin Backaction Thermometry for Modal Temperature Control
Yu-Hung Lai, Zhiquan Yuan, Myoung-Gyun Suh +3
Stimulated Brillouin scattering provides optical gain for efficient and narrow-linewidth lasers in high-Q microresonator systems. However, the thermal dependence of the Brillouin p…

Enhanced sensitivity operation of an optical gyroscope near an exceptional point
Yu-Hung Lai, Yu-Kun Lu, Myoung-Gyun Suh +1
Exceptional points (EPs) are special spectral degeneracies of non-Hermitian Hamiltonians governing the dynamics of open systems. At the EP two or more eigenvalues and the correspon…

Towards visible soliton microcomb generation
Seung Hoon Lee, Dong Yoon Oh, Qi-Fan Yang +7
Frequency combs have applications that extend from the ultra-violet into the mid-infrared bands. Microcombs, a miniature and often semiconductor-chip-based device, can potentially…
