Abstract
ABSTRACT Future generations of photonic devices which incorporate poled organic nonlinear optical materials may be aided by, or require the use of non-traditional electrodes. This report details the integration of highly doped silicon as one of the poling/modulating electrodes in the simple reflection type experiment for determination of nonlinear optical activity in a guest-host polymer system. The measurements illustrate that the behavior of doped-silicon and the traditional indium tin oxide (ITO) coated glass electrodes are analogous. Results demonstrate both successful poling and subsequent modulation of NLO materials using a silicon electrode, including the calculation of r 33 values comparable or exceeding those achieved using a standard ITO electrode. Keywords: electro-optic polymer, nonlinear optical polymer, silicon electrode, poling 1. INTRODUCTION Recent progress has seen the electro-optic (EO) activity of specially designed polymer systems achive new highs, easily surpassing lithium-niobate by a factor of at least two with respect to the critical figure of merit for the field, the electro-optic coefficient, r
