Get the concept of: polarization of light, dvoyakoprelomlenii, the anisotropy of optical properties, modulation of light, electro-optic modulator, PLZT element
Experiment: Monochromatic, vertically polarized light falls on the PLZT element (consisting of lead, lanthanum and titanium), fixed at an angle of 45 ° to the vertical. In the PLZT element the electric field, causing him to become birefringent. Recorded dependent phase shift between ordinary and extraordinary ray of light for the PLZT element of tension. It is proved that the phase shift is directly proportional to the square of the value of electric field, which depends on the voltage. From the coefficient of proportionality is calculated Kerr constant for PLZT element.
