Product Description

The Mechanical Three-ring Polarization Control is made by the principle of induced birefringence of optical fiber under external force.Three rings are equivalent to wave plates of ë/4,ë/2 and ë/4 respectively.Light waves are converted into linearly polarized light by ë/4 wave plates,then the polarization direction is adjusted by ë/2 wave plates.Finally,the polarization state of linearly polarized light is changed into arbitrary polarization state by ë/4 wave plates.The delay effect produced by the birefringence effect is mainly determined by the cladding radius of the fiber,the fiber ring radius and the wavelength of the light,the adjusted polarization state can cover the entire poincare sphere.

Features

Equivalent to ë/2, ë/4  optical wave plate
Adjustable to any point of polarization on the poincare sphere
Low insertion loss,wide wavelength range
Well-made,price moderate
Easy to disassemble ,self-replacement winding fiber

Applications

Single-mode to polarization-maintaining fiber
Measurement of polarization-dependent loss(PDL)
Application of polarization sensitive devices
Fiber laser
Fiber optic interferometer     


 

Mechanical Three-ring Polarization Controller's structure diagram

(Test unit:Diameter of  fiber loop is 40mm,diameter of fiber cladding is 125µm)
Example:The fiber loop with a fixed diameter of Polarization controller is 40mm,include single mode fiber of cladding diameter is 125µm)
When  λ=1550nm, loop number=1,go to λ/2 wave
When  λ=1550nm, loop number=3,go to 3 λ/2 wave
