Manual Mechanical 29mm Three-Ring Polarization Controller SM/PM Fiber Controller Customizable

Mechanical three-ring polarization control is made by using the principle of birefringence induced by optical fiber under the action of external force. Three of the rings are equivalent to three wave plates: λ/4 and λ/2. The light wave enters the λ/4 wave plate and is converted into linearly polarized light. The polarization direction is adjusted by the λ/2 wave plate, and finally passes through the λ/4 wave plate. λ/4 wave plate changes the polarization state of linearly polarized light into any polarization state. The delay effect caused by the birefringence effect is mainly determined by the cladding radius of the fiber, the fiber surrounding radius and the wavelength of the light wave. It has been verified that the controller can produce a full range of polarization state changes, and the adjusted polarization state can cover the entire Poincar sphere.
