Scientists have discovered novel optical properties in arsenic trisulfide (As2S3), a crystalline van der Waals semiconductor.
Crystalline arsenic trisulfide shows record photorefractive response and can be laser-patterned at 500-nm resolution without ...
Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different optical patterns at once is extremely complicated, and remains a major ...
The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence ...
Image showing gold contacts where we bias each laser with DC current. Light is out-coupled from the racetracks using the directional-coupler waveguides along the straight section of either racetrack.
