Chiral Flat-Band Optical Cavity with Atomically Thin Mirrors
Daniel G. Suárez-Forero, Ruihao Ni, Supratik Sarkar +10
A fundamental requirement for photonic technologies is the ability to control the confinement and propagation of light. Widely utilized platforms include two-dimensional (2D) optic…
Topological photonics: fundamental concepts, recent developments, and future directions
Mahmoud Jalali Mehrabad, Sunil Mittal, Mohammad Hafezi
Topological photonics is emerging as a new paradigm for the development of both classical and quantum photonic architectures. What makes topological photonics remarkably intriguing…
Topological Edge Mode Tapering
Christopher J. Flower, Sabyasachi Barik, Mahmoud Jalali Mehrabad +3
Mode tapering, or the gradual manipulation of the size of some mode, is a requirement for any system that aims to efficiently interface two or more subsystems of different mode siz…
Two-dimensional excitons from twisted light and the fate of the photon's orbital angular momentum
Tobias Graß, Utso Bhattacharya, Julia Sell +1
As the bound state of two oppositely charged particles, excitons emerge from optically excited semiconductors as the electronic analogue of a hydrogen atom. In the two-dimensional…
Topological Frequency Combs and Nested Temporal Solitons
Sunil Mittal, Gregory Moille, Kartik Srinivasan +2
Recent advances in realizing optical frequency combs using nonlinear parametric processes in integrated photonic resonators have revolutionized on-chip optical clocks, spectroscopy…
Tunable quantum interference using a topological source of indistinguishable photon pairs
Sunil Mittal, Venkata Vikram Orre, Elizabeth A. Goldschmidt +1
Sources of quantum light, in particular correlated photon pairs that are indistinguishable in all degrees of freedom, are the fundamental resource that enables continuous-variable…
