ASE light source is specially designed for laboratory experiment and production. The main part of the light source is gain medium erbium-doped fiber and high-performance pump laser. The unique ATC and APC circuits ensure the stability of the output power by controlling the output of the pump laser. By adjusting APC, the output power can be adjusted within a certain range. Simple and intelligent operation and remote control.

Optical devices packaged in TO are commonly referred to as coaxial devices. In active optical devices, coaxial devices mainly include coaxial optical transmission devices and coaxial optical reception devices.

Optical fibers are made of glass or plastic. Most are about the diameter of a human hair, and they can be many miles long. Light travels along the center of the fiber from one end to the other, and a signal can be applied. Fiber optic systems are superior to metal conductors in many applications. Their biggest advantage is bandwidth. Because of the wavelength of light, signals containing more information can be transmitted than metal conductors (even coaxial conductors

The fiber optic sensor network has three basic components, one of which is called a single-point sensor. An optical fiber only plays the role of transmission here, and the other is called a multi-point sensor, where one optical fiber connects many sensors together so that many sensors can share the light source to realize network monitoring. Then there is the smart fiber optic sensor. The multi-point optical fiber sensor is a grating from the outside, and periodic intervals are found through ultraviolet irradiation. When an optical fiber is incident, if the wavelength of the optical fiber is exactly twice the interval, the light wave will be strongly reflected, and if the optical fiber is subjected to temperature changes or strains, the reflected wavelength will change. This kind of sensor There can be many on one fiber, and it can be used for a variety of sensing applications by connecting them.

Semiconductor laser is a kind of laser developed in the 1960s, using semiconductor materials as working materials. Since the end of the 1970s, semiconductor lasers have clearly developed in two directions. One type is information-type lasers for the purpose of transmitting information, and the other type is power-type lasers for the purpose of directly using the optical power of the output laser.

An electro-optic modulator (EOM) is a device that controls the power, phase or polarization of an optical signal through an electrical signal. Its core principle is based on the linear electro-optic effect (Pockels effect). This effect manifests itself in that the applied electric field is proportional to the refractive index change of the nonlinear crystal, thereby achieving effective control of the optical signal.
