    • A new electro-optic (EO) phase modulator constructed from a combination of a low-loss passive polymer waveguide and a self-assembled chromophore superlattice (SAS) with an intrinsically polar microstructure. In contrast to typical polymer-based modulators, the present invention utilizes a siloxane SA methodology that enables the acentric alignment of constituent chromophores during film growth without the need for post-deposition electric field poling. The guiding layer is constructed of the SAS and the glassy polymer Cyclotene™. The use of SiO2, Cytop™ and Cyclotene™ glassy polymers, results in a straightforward device fabrication process that is compatible with the thermally and photochemically robust SAS. Thus, nanoscale control of the film architecture results in greatly simplified macroscopic device fabrication. The present invention provides a SAS-based electro-optic modulator demonstrating excellent electro-optic response properties and a &pgr; phase shift.
    • 由低损耗无源聚合物波导和具有固有极性微结构的自组装发光团超晶格(SAS)的组合构成的新的电光(EO)相位调制器。 与典型的基于聚合物的调节剂相反,本发明使用硅氧烷SA方法,其能够在膜生长期间能够进行组分发色团的定向配位,而不需要后沉积电场极化。 引导层由SAS和玻璃状聚合物Cyclotene TM构成。 使用SiO 2,Cytop TM和Cyclotene TM玻璃状聚合物可形成与热和光化学稳健的SAS相容的简单的器件制造工艺。 因此,膜结构的纳米尺度控制导致宏观器件制造的大大简化。 本发明提供了一种基于SAS的电光调制器,其表现出优异的电光响应特性和pi相移。
