1060nm Ase Broadband Light Source Manufacturers

A superradiance light source (also known as an ASE light source) is a superradiance-based broadband light source (white light source). (It is often mistakenly called a superluminescent light source, which is based on a different phenomenon called superfluorescence.) Generally, a superluminescent light source contains a laser gain medium that is excited to radiate light and then amplified to emit light.

In communications, Four Wave Mixing (FWM) is a coupling effect between light waves caused by the third-order polarization real part of the fiber medium. It is caused by the interaction of two or three light waves of different wavelengths at other wavelengths. The production of so-called mixing products, or new light waves in the sidebands, is a parametric nonlinear process. The reason for the four-wave mixing is that the light at a certain wavelength of the incident light will change the refractive index of the optical fiber, and the phase of the light wave will be changed at different frequencies, resulting in a new wavelength.

As one of the cores of medium and long-distance optical communication, the optical module plays a role in photoelectric conversion. It is composed of optical devices, functional circuit boards, and optical interfaces.

Erbium doped fiber is the core component of PA amplifiers, which amplifies optical signals by doping the rare earth element erbium (Er) into the fiber core.

Compared with discrete optical fiber amplification technology, Distributed Raman Amplification (DRA) technology has shown obvious advantages in many aspects such as noise figure, nonlinear damage, gain bandwidth, etc., and has gained advantages in the field of optical fiber communication and sensing. widely used. High-order DRA can make the gain deep into the link to achieve quasi-lossless optical transmission (that is, the best balance of optical signal-to-noise ratio and nonlinear damage), and significantly improve the overall balance of optical fiber transmission/sensing. Compared with conventional high-end DRA, DRA based on ultra-long fiber laser simplifies the system structure, and has the advantage of gain clamp production, showing strong application potential. However, this amplification method still faces bottlenecks that restrict its application to long-distance optical fiber transmission/sensing
