Petermann-factor limited sensing near an exceptional point
Heming Wang, Yu-Hung Lai, Zhiquan Yuan +2
Non-Hermitian Hamiltonians describing open systems can feature singularities called exceptional points (EPs). Resonant frequencies become strongly dependent on externally applied 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…
