3 Paddle Mechanical Polarization Controller
Description：
3 Paddle Mechanical Polarization Controller is use fiber outside pressure and birefrigent
effect theory. Its 3 Paddle is respectively equalλ/4、λ/2、λ/4 plate. When light wave
entersλ/4 waveplate is transfer line polarization, then useλ/2 is adjust Polarization
direction, finally it enters toλ/4 waveplate and line polarization state is change to any
polarization. Due to Birefrigent’s delay effect is come from fiber cladding, roll fiber,
and wavelength. It can generate all polarization change.
Feature:

For device with connector, IL is 0.3dB higher, RL is 5dB lower.
Polarization Controller’s Single Paddle Delay and Wavelength, Roll relationship-
(Measure unit: Fiber roll diameter 29mm, Fiber cladding diameter 125um)
For example:
Whenλ=1550nm, Loop =1, its paddle is equalλ/2 waveplate
When λ=1550nm, Loop=3, its paddle is equal 3λ/2 waveplate
