Optical EngineeringPLZT modulator characterization
|Format||Member Price||Non-Member Price|
A commercial PLZT modulator is characterized at wavelengths from 0.6328 μm to the limits of its IR transmission around 9 μm. Laser polarimetry and IR spectropolárimetry are the characterization techniques used. Polarization measurement results include diattenuation and retardation. The PLZT modulator is found to be an electrically controllable polarizer as well as an electrically controllable retarder.
