Abstract :
We describe the fabrication and performance of a thin-film electro-optic Fabry-Perot modulator operating in reflection, at wavelengths compatible with silicon detectors, fabricated on a silicon substrate. A nonlinear polymer is used with a low dielectric constant that permits an electrical bandwidth in excess of 100 MHz with low modulating energy. Existing thin-film fabrication techniques and materials are used to demonstrate device performance. We report modulation of approximately 1.5% and describe foreseen improvements in nonlinear polymers and technology which promise in excess of 5% modulation with a 5 V modulating voltage.<>
