Types of laser modulators
First, Internal modulation and external modulation According to the relative relationship between the modulator and the laser, the laser modulation can be divided into internal modulation and external modulation. 01 internal modulation The modulation signal is carried out in the process of laser ...Read More -
Current situation and hot spots of microwave signal generation in microwave optoelectronics
Microwave optoelectronics, as the name suggests, is the intersection of microwave and optoelectronics. Microwaves and light waves are electromagnetic waves, and the frequencies are many orders of magnitude different, and the components and technologies developed in their respective fields are ver...Read More -
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 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 -
