Optoelectronic devices and components are those electronic devices that operate on both light and electrical currents. This can include electrically driven light sources such as laser diodes and light-emitting diodes, components for converting light to an electrical current such as solar and photovoltaic cells and devices that can electronically control the propagation of light.
The integration of transition metal thio/selenophosphates (TPS) like CuInPS and CuCrPS onto Silicon Photonics marks a significant advancement in optical devices. This innovation provides precise control over refractive index, minimizes optical losses, enhances modulation efficiency, and reduces the footprint for next-generation optoelectronics.
Researchers demonstrate a germanium/silicon avalanche photodiode gain–bandwidth product over 1 THz operating at 1,550 nm wavelength. The findings have implications for future high-speed optoelectronic devices in next-generation optical interconnects.
Dual-channel mechano-phosphorescence, characterized by dual emission and ultralong organic phosphorescence, was achieved by strengthening the intra- and intermolecular interactions in the highly twisted structures to realize a combined locking effect.
Electrical excitation of a perovskite light-emitting diode is shown to contribute to optical gain, a milestone on the path towards a non-epitaxial laser diode.
New conductive and perovskite inks enable hand-drawing of optoelectronic devices with a ballpoint pen on a variety of daily substrates, including paper, textiles and other irregular surfaces.
