Polarization Maintaining Dual Fiber Collimator (GK-HPPMC Series)

The Polarization Maintaining Dual Fiber Collimator is a specialized optical component designed to work with polarization maintaining (PM) fiber optics. It serves as a fundamental building block for in-line PM fiber optic components such as PM isolators and PM free-space wavelength division multiplexers (FWDM). Here's a summary of its key features:

This feature indicates the ability of the collimator to effectively separate or combine different polarizations. A high extinction ratio is crucial for applications where the polarization state of light must be controlled, such as in certain types of optical sensors or quantum communication systems.

The collimator is designed to minimize the loss of light power as it is coupled into or out of the fiber. This ensures that the light signal remains strong and reliable throughout the optical system.

This refers to the ability of the collimator to reflect back any light that is not transmitted, which helps to reduce reflections and ghosting in the optical system. High return loss is important for maintaining signal integrity and reducing noise.

The collimator is capable of handling high power levels without significant degradation. This is achieved through unique processing techniques and high-quality anti-reflective (AR) coatings, which protect the collimator from damage and ensure consistent performance even at high power levels.
