Paper Abstract

Electro-optic modulators (EOM's) can be used for polarization modulation of light at frequencies up to hundreds of megahertz and are therefore strong candidates for high speed effipsometer systems. The characteristic of this device is the half wave voltage, V ,which is a function of the wavelength of light and the temperature. A description of the particular ADP EOM we are using, and a discussion of the effect of laser linewidth and temperature on the measurement of V,, is presented. For the laser diode wavelength of )t = 830 nm, V, and the extinction ratio are measured at different temperatures.
