Optical fiber amplifier is a new all-optical amplifier used in optical fiber communication line to realize signal amplification. According to its position and function in the optical fiber line, it is generally divided into relay amplification, pre amplification and power amplification.

Visible light sources, spanning wavelengths from 400nm (violet) to 760nm (red), are indispensable in modern manufacturing, healthcare, and research. With precise wavelength control and stable output, these sources power everything from high-precision imaging to vibrant displays.

People utilized this ASE process to make broadband ASE light source which is essential for many different telecommunications, fiber sensing, fiber optic gyroscope, and test & measurement applications.

Optical Coherence Tomography (OCT) is a low-loss, high-resolution, non-invasive medical and imaging technology developed in the early 1990s. Its principle is similar to ultrasound imaging, the difference is that it uses light instead of sound.

Fiber Laser refers to a laser that uses rare earth-doped glass fiber as the gain medium. Fiber lasers can be developed on the basis of fiber amplifiers. High power density is easily formed in the fiber under the action of pump light, resulting in laser The laser energy level of the working substance is "population inversion", and when a positive feedback loop (to form a resonant cavity) is properly added, the laser oscillation output can be formed.

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.
