Optical Valley Hall Effect of 2D Excitons in Hyperbolic Metamaterial
Sriram Guddala, Mandeep Khatoniar, Nicholas Yama +3
The robust spin and momentum valley locking of electrons in two-dimensional semiconductors make the valley degree of freedom of great utility for functional optoelectronic devices.…
All-optical nonreciprocity due to valley polarization in transition metal dichalcogenides
Yuma Kawaguchi, Sriram Guddala, Kai Chen +3
Nonreciprocity and nonreciprocal optical devices play a vital role in modern photonic technologies by enforcing one-way propagation of light. Most nonreciprocal devices today are m…
Direct visualization of topological transitions and higher-order topological states in photonic metasurfaces
Anton Vakulenko, Svetlana Kiriushechkina, Mengyao Li +6
Topological photonic systems represent a new class of optical materials supporting boundary modes with unique properties, not found in conventional photonics. While the early resea…
Valley selective optical control of excitons in 2D semiconductors using Chiral metasurface
S. Guddala, R. Bushati, M. Li +2
Recent advances in condensed matter physics have shown that the valley degree of freedom of electrons in 2D materials with hexagonal symmetry, such as graphene, h-BN, and TMDs, can…
