1064nm In-Line Fiber Optic Depolarizers With PM Fiber PM Optical Depolarizer

1064nm In-Line Fiber Optic Depolarizers With PM Fiber PM Optical Depolarizer

The function of the fiber depolarizer coaxial polarizer is to convert unpolarized light into linearly polarized light to obtain a higher extinction ratio, and is used to improve precision measurement systems, fiber optic sensors, high-speed test instruments, etc. that require high extinction ratios. The extinction ratio of the signal.

In-line depolarizers have the characteristics of low insertion loss, high repeatability, and high stability and are mainly used in broadband light sources, optical fiber sensing, optical amplifier applications, etc.

A depolarizer works by splitting an input beam into two orthogonally polarized beams of equal power, delaying one beam relative to the other, and then recombining the two beams using a polarization combiner. The relative retardation between orthogonally polarized beams is greater than the coherence length of the light source, thereby eliminating the fixed phase relationship between the two beams when they are recombined.
