Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings

Advanced Photonics Research, EarlyView.
The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...

Giant Modulation of Interlayer Coupling in Twisted Bilayer ReS2

Advanced Science, EarlyView.
Twist angle in stacked bilayer ReS2 can modulate 30% of interlayer coupling and the whole range of exciton energy between 1L and 2L ReS2. Abstract Stacking monolayers of two‐dimensional (2D) transition metal dichalcogenides with different twist angles can provide a way to tune their quantum optical and electronic characteristics.
