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.
We developed a phase plate for which the phase can be changed within microseconds, which enables building a fast, simple and stable MINFLUX microscope.
Sylvain Guerber and colleagues present a method for biaxial beam steering with an optical phased array integrated within a piezoelectric activated MEMS cantilever. This approach is helpful to avoid the use of a tunable laser to achieve 2D beam steering.
A modular quantum system-on-chip architecture integrates thousands of individually addressable spin qubits in two-dimensional quantum microchiplet arrays into an integrated circuit designed for cryogenic control, supporting full connectivity for quantum memory arrays across spin–photon channels.
The authors demonstrate ultrabroadband, polarisation-independent directional control of thermal radiation using a pixelated micro-emitter, and produce large emissivity contrast at different directions, with potential applications to radiative cooling, infrared spectroscopy and thermophotovoltaics.
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.
