Fabrication and Characterization of Arrays of GaAs All-Optical Logic Gates [PDF]

, 1986
Optical bistable elements fabricated from gallium arsenide (GaAs) have demonstrated potential as optical logic elements for use in optical parallel processing systems [1]. In previous experiments, the devices have consisted of small, uniform slabs of active material, either bulk GaAs or GaAs-AlGaAs multiple-quantum-well structures [2].

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

Advanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.
