Fiber-optic Gyroscopes: The low coherence of ASE light sources can suppress nonlinear effects, improving the accuracy and stability of inertial navigation systems. Wavelength Division Multiplexing (WDM) Device Testing: Broadband light sources cover multiple communication bands, supporting simultaneous testing of multi-channel insertion loss, isolation, and OSNR (Optical Signal-to-Noise Ratio).
In the field of optical communications, long-distance transmission has long been challenged by issues such as signal attenuation and distortion. Raman fiber amplifiers, with their unique advantages, have become a key technology for improving the performance of long-distance optical communication systems.
International media recently reported that scientists at the Harvard John A. K. Howe School of Engineering and Applied Sciences, in collaboration with the Technical University of Vienna, have developed a new semiconductor laser. This laser utilizes a simple crystal design and enables efficient, reliable, and versatile wavelength transmission.
The three main functional components of a laser are the pump source, the gain medium, and the resonant cavity.
An EDFA is a fiber amplifier based on the erbium-doped fiber principle. It boasts advantages such as a wide wavelength range, high amplification gain, low noise, and high reliability. It is widely used in optical communication systems.
A tunable fiber laser is a fiber laser device capable of continuously adjusting the output laser wavelength. Wavelength tuning is achieved by changing internal structural parameters or through external control. It is widely used in scientific research, industry, medicine, and other fields.
