In this paper, we report a novel technique that combines push-pull Mach-Zehnder modulator structure with dc bias to achieve fractional volt half-wave voltage in intensity modulation. The technique is accomplished by simultaneously applying a common m

Organic materials have great potential for electro-optic devices. Achieving higher unidirectional ordering of chromophores is the main challenge in using organic materials in such devices. The prime reason for this decreased order is due to interchro

Previous research in organic electro-optics has shown dramatic increases in the hyperpolarizablity of NLO chromophores. However, this large microscopic activity has not been translated to the macroscopic domain. The polymeric electro-optic (E-O) mate

In order to achieve the near-ferroelectric order desired in organic electro-optic (EO) chromophore systems, a pseudo-discotic chromophore is under investigation. Calculations suggest head-to-tail inter-chromophore dipole-dipole interactions should dr
