Toward nanophotonic platforms for solid-state Th nuclear clocks
Sandro Kraemer, Karen Mamian, Toby Bi +18
While the Th nuclear isomer has recently been observed and laser-excited, converting optical nuclear manipulation into a chip-scale solid-state frequency standard remains a…
Fourth-harmonic UV light generation in integrated silicon nitride microresonators
Alekhya Ghosh, Arghadeep Pal, Haochen Yan +6
Integrated silicon nitride (Si3N4) resonators have emerged as a leading platform for nonlinear photonics, yet generating light at wavelength in the ultraviolet (UV) has remained el…
Color symmetry breaking in a nonlinear optical microcavity
Luca O. Trinchão, Alekhya Ghosh, Arghadeep Pal +8
Spontaneous symmetry breaking leads to diverse phenomena across the natural sciences, from the Higgs mechanism in particle physics to superconductors and collective animal behavior…
Scattering Induced Mode Chirality in Ring Resonators
Haochen Yan, Xu Guo, Arghadeep Pal +15
Non-Hermitian physics can be used to break time reversal symmetry and is important for interactions in a wide range of systems, from active matter and neural networks to metamateri…
Visualization of nonlinear optics in a microresonator
Hao Zhang, Haochen Yan, Alekhya Ghosh +10
A precise understanding of nonlinear optical phenomena in whispering gallery mode (WGM) microresonators is crucial for developing next-generation integrated photonic devices. Appli…
Simplified Aluminum Nitride Processing for Low-Loss Integrated Photonics and Nonlinear Optics
Haochen Yan, Shuangyou Zhang, Arghadeep Pal +12
Aluminum nitride (AlN) is an extremely promising material for integrated photonics because of the combination of strong \c{hi}2 and \c{hi}3 nonlinearities. However, the intrinsic h…
