Quantum communication: molecules, rare earths and optical
Quantum information technology is a new information technology based on quantum mechanics, which encodes, computes and transmits the physical information contained in quantum system. The development and application of quantum information technology will bring us into the “quantum age”...Read More -
Eo modulator Series: High speed, low voltage, small size lithium niobate thin film polarization control device
Eo modulator Series: High speed, low voltage, small size lithium niobate thin film polarization control device Light waves in free space (as well as electromagnetic waves of other frequencies) are shear waves, and the direction of vibration of its electric and magnetic fields has various possible...Read More -
Experimental separation of wave-particle duality
Wave and particle property are two basic properties of matter in nature. In the case of light, the debate over whether it is a wave or a particle dates back to the 17th century. Newton established a relatively perfect particle theory of light in his book Optics, which made the particle theory of ...Read More -
What is an electro-optic modulator optical frequency comb?Part Two
02 electro-optic modulator and electro-optic modulation optical frequency comb Electro-optical effect refers to the effect that the refractive index of a material changes when an electric field is applied. There are two main kinds of electro-optical effect, one is the primary electro-optical effe...Read More -
What is an electro-optic modulator optical frequency comb?Part One
An optical frequency comb is a spectrum composed of a series of evenly spaced frequency components on the spectrum, which can be generated by mode-locked lasers, resonators, or electro-optical modulators. Optical frequency combs generated by electro-optic modulators have the characteristics of hi...Read More -
Eo Modulator Series: cyclic fiber loops in laser technology
What is “cyclic fiber ring”? How much do you know about it? Definition: An optical fiber ring through which light can cycle many times A cyclic fiber ring is a fiber optic device in which light can cycle back and forth many times. It is mainly used in long distance optical fiber commu...Read More -

Narrow Linewidth Laser Technology Part Two
Narrow Linewidth Laser Technology Part Two (3) Solid state laser In 1960, the world’s first ruby laser was a solid-state laser, characterized by a high output energy and a wider wavelength coverage. The unique spatial structure of solid-state laser makes it more flexible in the design of na...Read More -
Narrow linewidth laser technology Part One
Today, we will introduce a “monochromatic” laser to the extreme – narrow linewidth laser. Its emergence fills the gaps in many application fields of laser, and in recent years has been widely used in gravitational wave detection, liDAR, distributed sensing, high-speed coherent o...Read More -
