  • 1X2 Polarization Beam Combiner Splitter

    1X2 Polarization Beam Combiner Splitter

    1X2 Polarization Beam Combiner Splitter is designed to either combine or split linearlypolarized light. When used as a combiner, the linearly polarized input lights are combined into a single output with two orthogonal linear polarizations. When used as a splitter, an input light with two orthogonal linear polarizations is split into two outputs each with a single linear polarization. These polarization beam combiners are frequently utilized to combine the light from two pump lasers into a single fiber to increase the power input to an erbium-doped fiber amplifier or Raman amplifier.

  • Application of Fiber Random Laser in Distributed Sensing

    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

  • How to test the transmittance and reflectance of optical components?

    When the incident light flux leaves from the illuminated surface or the incident surface of the medium to the other side, the ratio of the radiant energy projected and transmitted through the object to the total radiant energy projected on the object is called the transmittance of the object. The percentage of radiant energy reflected by an object to the total radiant energy is called reflectivity.

  • Fiber Optical Amplifier

    Fiber Optical Amplifier is a kind of optical amplifier using optical fiber as gain medium. Typically, the gain medium is fiber doped with rare earth ions, such as erbium (EDFA, Erbium-Doped Fiber Amplifier), neodymium, ytterbium (YDFA), praseodymium and thulium. These active dopants are pumped (provided with energy) by light from a laser, such as a fiber-coupled diode laser; in most cases, the pump light and the amplified signal light travel simultaneously in the fiber core.
