What is a spatial light modulator?
Spatial light modulator means that under active control, it can modulate some parameters of light field through liquid crystal molecules, such as modulating the amplitude of light field, modulating the phase through the refractive index, modulating the polarization state through the rotation of ...Read More -
What is optical wireless communication?
Optical Wireless Communication (OWC) is a form of optical communication in which signals are transmitted using unguided visible, infrared (IR), or ultraviolet (UV) light. OWC systems operating at visible wavelengths (390 — 750 nm) are often referred to as visible light communication (VLC). ...Read More -

Principle and progress of quantum communication technology
Quantum communication is the central part of quantum information technology. It has the advantages of absolute secrecy, large communication capacity, fast transmission speed, and so on. It can complete the particular tasks that classical communication can not achieve. Quantum communication can us...Read More -
Principle and classification of fog
Principle and classification of fog (1)principle The principle of fog is called Sagnac effect in physics. In a closed light path, two beams of light from the same light source will be interfered when they are converged to the same detection point. If the closed light path has rotation relati...Read More -
The working principle of directional coupler
Directional couplers are standard microwave/millimeter wave components in microwave measurement and other microwave systems. They can be used for signal isolation, separation, and mixing, such as power monitoring, source output power stabilization, signal source isolation, transmission and refl...Read More
