Optics and photonics is the study of the fundamental properties of light and harnessing them in practical applications. Optics and photonics covers the entire electromagnetic spectrum from high-energy gamma rays and X-rays, through the optical regime of ultraviolet, visible, and infrared light, to long-wavelength microwave and radio waves.
Photoresponsive perovskite light-emitting diodes can be used to build multifunctional displays that can function as touch screens, light sensors and image sensors.
A single monolayer semiconductor integrated into a plasmonic tunnel junction exhibits electroluminescence with photon energies that exceed the excitation electron potential. This phenomenon is shown to be indirectly triggered by inelastically tunnelling electrons.
A single light-emitting dye molecule precisely placed within the tiny gap of a metal nanodimer boosts light–matter coupling — a step closer to the development of quantum devices operating at room temperature.
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.
By resonant pumping the organic cation in 2D perovskite, Fu et al. report the electronic and mechanical couplings between the organic and inorganic sublattices, evidenced by the reduced bandgap and modified lattice degree of freedom within the inorganic sublattice, and slow heat transfer process.
Inspired by the human visual system, a vision chip with primitive-based complementary pathways is developed to overcome the power and bandwidth wall of vision systems, achieving fast, precise, robust and high-dynamic-range sensing efficiently in the open world.
The Sanya incoherent scatter radar (SYISR) system has now been augmented to become the world’s first phased-array tristatic ISR system, enabling it to sense volumes of the Earth’s ionosphere, explain the SYISR-TS leadership team.
