Abstract
An electro-optic (EO) switch based on a Fabry-Perot resonator design was fabricated and tested. The switch is comprised of two high index glass substrates with indium tin oxide (ITO) coated Bragg mirrors, surrounding an electro-optic polymer layer. The ITO top layers were patterned, the electro-optic polymer, SEO100 (Soluxra Inc.), was spun coat onto each of the two Bragg substrates, and the two samples were wafer bonded. The sandwich device was then electric field poled using a field between 80 and 90 V/μm in order to induce a second-order nonlinear optical activity in the electrooptic polymer. The experimental results done at 1.31 micron laser wavelength with a drive voltage of ±200 volts yielded a modulation depth of around 86% and 80% for frequencies of 1kHz and 10kHz, respectively.
