9423666 Cronin-Golomb本研究的目的是研究使用等离子体增强金属有机化学气相沉积（PE-CVD）生长的电光和光折变薄膜作为非线性光波导器件。 潜在的应用包括紧凑型自对准可重构光互连和开关以及紧凑型高速电光调制器。 这个塔夫茨大学/新西兰应用技术项目将作为具有光折变非线性光学专业知识的大学研究人员和具有钙钛矿PE-CVD专业知识的工业研究人员之间的合作进行。该项目的第一部分将致力于开发PE-CVD生长的铁电钙钛矿钛酸钡和钛酸锶钡的外延膜。薄膜将作为波导进行评估，将确定光折变和电光响应的品质因数，并将研究它们作为相位共轭镜和光束耦合器的用途。薄膜将生长在各种基板上，以确定那些可能是适合于直接集成的光折变薄膜器件到光电集成电路。 ***

9423666 Cronin-Golomb The object of this research is to investigate the use of plasma enhanced metalorganic chemical vapor deposition (PE-CVD) grown electro-optic and photorefractive thin films as nonlinear optical waveguide devices. Potential applications include compact self-aligning reconfigurable optical interconnects and switches and compact high speed electrooptic modulators. This Tufts University/NZ Applied Technologies project will be performed as a collaboration between university researchers with expertise in photorefractive nonlinear optics and researchers in industry with expertise in perovskite PE-CVD. The first part of the project will be devoted to developing PE-CVD grown epitaxial films of the ferroelectric perovskites barium titanate and strontium barium niobate. The films will be evaluated as waveguides, figures of merit for photorefractive and electro-optic response will be determined, and their use as phase conjugate mirrors and beam couplers will be studied. The films will be grown on various substrates to determine those which might be suitable for direct integration of photorefractive thin film devices into optoelectronic integrated circuits. ***
