Abstract

Fabry-Ṕrot interferometers (FPIs) are designed to work near and off the absorption resonance of an electro-optic (EO) polymer. The near-resonance EO activity (EO coefficient r13 ∼25.4 pmV at ∼1086 nm) is enhanced over that off resonance (r13 ∼9.0 pmV at ∼1526 nm). The full width at half maximum of the FPI transmission band is ∼16 nm near resonance compared to ∼22 nm off resonance. The modulation performance can, therefore, be improved with a modulation ratio increased to ∼78% near resonance (at 1064 nm) from ∼19% off resonance (at 1520 nm). The modulation speed is approximately megahertz and can be increased to greater than gigahertz with improved circuit design.
