Polarization Beam Combiner/Splitter (GK-IPBC/IPBS Series)

The Isolator Polarization Beam Combiner/Splitter is a compact device which provides both polarization beam combining and optical isolation in one integrated component. The most common application is to combine the light of two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. IPBC/IPBS has extremely low insertion loss, and it can improve the amplifier performance.

product description

The GKER Photonics Polarization Beam Combiner/Splitter (GK-PBC/PBS Series) is a compact, high-performance optical component designed to either combine or split light based on polarization. It is specifically engineered to merge two orthogonal polarization signals into a single output fiber, which is particularly valuable in applications such as EDFA (Erbium-Doped Fiber Amplifiers) or Raman Amplifiers, where combining the output of two pump lasers into one fiber significantly enhances power output.

This versatile device can also function as a beam splitter, separating incoming light into two polarization components. The Polarization Beam Combiner/Splitter is built with precision to ensure minimal insertion loss, high extinction ratio, and excellent return loss, making it ideal for use in high-power optical systems.

The device is available in various configurations, including different operating wavelengths, fiber types, and connector options, allowing for seamless integration into existing optical networks. With its robust design and reliable performance across a broad temperature range, the GK-PBC/PBS Series is an essential component for optimizing optical signal management in advanced photonic systems.
