product description
The design purpose of an In Line Polarizer is to allow light of a specific polarization direction to pass through while blocking light of other polarization directions. This design enables the inline polarizer to convert non polarized light into polarized light with a high extinction ratio, where extinction ratio is a key parameter for measuring the performance of the polarizer, which characterizes its ability to obtain linear polarization
Linear polarizers utilize their excellent polarization properties to improve the extinction ratio of signals, which is crucial for high-speed communication systems and testing instruments that require high polarization extinction ratios.
The high extinction ratio of an inline polarizer means that it can effectively suppress unwanted polarization states of light, thereby improving the quality and reliability of the signal. Polarization control is crucial for the stability and bit error rate of high-speed communication systems. For example, the high-speed polarization control scheme in all fiber quantum communication systems precisely controls the polarization direction of the optical field by adjusting the phase difference of the fiber optic electro-optic phase modulator, achieving the output of various polarization states from a single port without the need for subsequent coupling operations. Its phase control accuracy is 10 ^ -3 rad, the maximum extinction ratio can reach 30 dB, and the operating rate can reach 2 GHz
In addition, the environmental stability of the inline polarizer is also an important characteristic, which ensures that the performance of the polarizer remains stable under different environmental conditions, which is particularly important for fiber lasers and testing instruments that need to operate in variable environments. The low insertion loss and low polarization dependence of the inline polarizer also help ensure efficient transmission and high-quality retention of signals when passing through the polarizer.
Overall, the design and characteristics of inline polarizers make them an indispensable component in high-speed communication systems and testing instruments. They improve the overall performance and reliability of the system by precisely controlling the polarization state of light.
