Abstract

Polymeric second-order nonlinear optical (NLO) materials have been studied extensively in recent years for applications in electrooptic devices [1,2]. There are three types of polymer materials developed for this purpose: guest-host systems [3], side-chain polymers [4-6], and main-chain polymers [7-9]. The second-order NLO effects of these materials were demonstrated after electric poling above the polymer glass transition temperature (T_g). While many guest-host and side-chain NLO polymers have been developed, relatively few main-chain polymers have been prepared. Most of the main-chain polymers reported are heat-to tail; namely, all the Chromophore dipole moments point in the same direction along the polymer main chain.
