Reflective planar microcavity with enhanced electro-optic activity of a poled polymer

摘要

We investigated the enhancement of the voltage-induced phase difference by embedding an electro-optic (EO) polymer into a reflective planar microcavity in a reflection ellipsometric configuration. We fabricated the microcavity with efficient light localization in the EO polymer and evaluated the resultant enhancement of voltage-induced phase-difference between s- and p-polarized components. We obtained 48 times larger phase-difference than that for the EO polymer only. The enhancement was attributed to the polarization-dependent local field effect for oblique incidence.
