Photonic devices are components for creating, manipulating or detecting light. This can include laser diodes, light-emitting diodes, solar and photovoltaic cells, displays and optical amplifiers. Other examples are devices for modulating a beam of light and for combining and separating beams of light of different wavelength.
A new design of electron gun that uses terahertz waves to accelerate electrons in a high field gradient brings a tabletop answer to the generation of ultrashort electron bunches.
This study proposes the “discrete preparation-multilayer lamination” strategy, which effectively addresses the challenges associated with vertically stacked skin-like AMOLEDs and demonstrates their potential for next-generation wearable displays.
A memristive-photoconductive transduction (MPT) behavior was firstly observed in a memristor based on porous P3HT, which is the direct signal for cell resistance states detection, enabling accurate and nondestructive readout.
Coherent interconversion between microwave and optical frequencies is crucial for developing quantum networks. To this end, the authors integrate piezoelectric actuators on photonic integrated circuits, enabling bidirectional transduction mediated by high-overtone bulk acoustic resonances.
In-sensor computing architectures can provide energy-efficient multifunctional capabilities, but their application to the mid-infrared range is challenging. Here, the authors report the realization of non-volatile MoS2/black phosphorus photovoltaic detectors, integrating near- to mid-infrared photodetection, memory and computing functionalities.

A large-angle twist between two bilayer graphene films makes a sensitive and broadband infrared–terahertz detector as a result of interlayer screening and a crystal field-induced bandgap.
