Objective: This program uses new advances in ultrathin ferroelectric-film fabrication, nano-poling, and simulation methods for nonlinear-optical devices, to realize new tunable photonic-crystal devices.Intellectual Merit: This photonics program will investigate a new class of tunable second-order optical susceptibility nano-photonic device, by nano-structuring ferroelectric thin-film photonic crystals to tailor their optical response. The main challenges are ultrahigh-resolution poling, electrode-structure design, and thin-film device implementation. Key elements are nano-fabrication methods, design and testing of the tunable crystals, and two model-device fabrications. Its transformative aspect arises from its nanometer scale, providing unprecedented control of phase matching due to light confinement.Broader Impacts: This program involves photonic devices, an area with broad impact for sensors in medical and biological science, data transmission and processing, and metrology. The research will be integrated into the education mission of Columbia and the University at Albany to foster an interdisciplinary examination of artificial nonlinear metamaterials and to enable the two groups with a strong history of interactions to collaborate. This work will involve students interaction and travel to their partner universities. The program will recruit diverse student collaborators. Recruitment will be done via five yearly outreach talks to undergrads at Columbia and Albany and participation in Undergraduate Research Opportunities Program at Columbia. The project will enable students to collaborate with the Nanocenter at Brookhaven National Laboratory, which one of the PIs was the founding director, and with the Ion-Beam Facility at Albany. This program involves overseas research collaboration with University of Bonn (Soergel) and University College London (Panoiu).This project is jointly funded by the Electronics, Photonics, and Magnetic Devices Program (EPMD) in the Division of Electrical, Communications and Cyber Systems (ECCS) and by the Electronic and Photonic Materials Program (EPM) in the Division of Materials Research (DMR).

目的：本项目利用铁电薄膜制备、纳米极化和非线性光学器件模拟方法的最新进展，实现新型可调光子晶体器件。学术价值：本项目将研究一类新型可调二阶光学极化率纳米光子器件，通过纳米结构铁电薄膜光子晶体来调整其光学响应。主要的挑战是超高分辨率极化，电极结构设计，和薄膜器件的实现。关键要素是纳米制造方法，可调晶体的设计和测试，以及两个模型设备制造。其变革性的一面源于其纳米尺度，由于光限制，提供了前所未有的相位匹配控制。更广泛的影响：该计划涉及光子器件，这是一个对医学和生物科学，数据传输和处理以及计量学中的传感器具有广泛影响的领域。这项研究将被纳入哥伦比亚大学和奥尔巴尼大学的教育使命，以促进人工非线性超材料的跨学科研究，并使两个具有强大相互作用历史的团体能够合作。这项工作将涉及学生的互动和前往他们的合作伙伴大学。该计划将招募不同的学生合作者。招聘将通过五年一次的外联会谈，在哥伦比亚和奥尔巴尼的本科生和参与本科研究机会计划在哥伦比亚完成。该项目将使学生能够与布鲁克海文国家实验室的纳米中心合作，其中一个PI是创始主任，并与奥尔巴尼的离子束设施合作。该项目由德国波恩大学（Soergel）和伦敦大学学院（Panoiu）共同资助，由电气、通信和网络系统部（ECCS）的电子、光子学和磁器件项目（EPMD）和材料研究部（DMR）的电子和光子学材料项目（EPM）共同资助。
