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…
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…
Inverse-Designed Silicon Nitride Nanophotonics
Toby Bi, Shuangyou Zhang, Egemen Bostan +12
Silicon nitride photonics has enabled integration of a variety of components for applications in linear and nonlinear optics, including telecommunications, optical clocks, astrocom…
Hybrid Nonlinear Effects in Photonic Integrated Circuits
Arghadeep Pal, Alekhya Ghosh, Shuangyou Zhang +5
Nonlinear optics in photonic integrated circuits is usually limited to utilizing the nonlinearity of a single material. In this work, we demonstrate the use of hybrid optical nonli…
