Reflectance modulator utilizing an electro-optic polymer film

Abstract
Device fabrication and experimental results are reported for a reflectance modulator in which coupling between a 632.8 nm laser beam reflected from the base of a prism and a guided mode in an electro-optic polymer is electrically varied. The beam intensity was varied ±31% by application of 46 V rms across the polymer. The response is independent of frequency up to at least 5 MHz.
