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 diminutive 3D nano-printed photonic lantern supporting multiplexing of six input sources to a six-mode optical fiber is demonstrated, at 375 μm total length, exhibiting low insertion, polarization and mode-dependent loss.
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.
