Analysis of generalized principal state of polarization and the piezoelectric polarization control system

Generalized principal state of polarization (PSP) is proposed to analyse the piezoelectric polarization controller (PPC) and demonstrated by experiment. We find the generalized PSP is a constant in a given PPC unit and the output state of polarization (SOP) is expressed as a cosine function of driving voltage with its validity analysed. Then the polarization control system is established based on the PPC with three units and some of the its characteristics are investigated. Results show the PSPs of three PPC units are approximately orthogonal to each other, and the polarization response time of our PPC is about 40 μs, which will improve significantly the control speed of polarization control system.
