项目摘要

Modern optical communication networks suffer from fundamental limitations of electronic signal processing due to the limited bandwidth. All-optical signal processing is necessary to overcome these limitations, as optical materials exhibit much broader bandwidth compared to that available in electronic signal processing. All-optical signal processing relies fully on nonlinear optical interactions of light with matter. Such interactions result in the appearance of new spectral components and the modifications of the optical response of the medium supporting the propagation of the optical beams. The appearance of new frequencies in the optical spectrum of the information streams is crucial for wavelength conversion used for transferring the information channels from one frequency band to another. The modifications of the optical media’s response by nonlinear interactions are necessary for optical switching of the information streams between physically separated channels; it can occur nearly instantly, much faster than electrical switching.Another target area that can benefit from nonlinear optical interactions is quantum information. In quantum communication networks, one can securely encode and transmit information. Quantum information fully relies on generation of correlated (entangled) photon pairs. Such photon pairs can be produced through nonlinear optical interactions, decomposing (down-converting) an optical beam into two beams with new frequencies.The goal of the proposed research program is to develop nanophotonic devices and nanostructured materials aimed at producing highly efficient nonlinear optical interactions for all-optical signal processing in optical communication networks, and for the field of quantum information. Several approaches will be pursued towards the realization of enhancement in nonlinear optical response of photonic materials and devices. The first approach includes engineering integrated optical devices and photonic nanostructures to produce the desired enhancement. The second approach is material-based; it relies on the physics of the nonlinear optical response of nanocomposite optical materials which are nanoscale mixtures of two or more homogeneous constituents. The size of individual grains in such materials is much smaller than the wavelength of light, and the electrostatic optical field redistribution with the localization in the component with the higher optical nonlinearity can be achieved by a proper tailoring. Combining the two approaches is expected to result in dramatic enhancements of the optical nonlinearity, opening up the route to new interesting physics and practical applications. The implementation of the enhanced nonlinear optical response in integrated optical components for all-optical signal processing, as well as in producing integrated quantum optics networks is an ultimate goal of the proposed research program.
由于有限的带宽,现代光通信网络遭受电子信号处理的根本限制。全光信号处理是克服这些限制所必需的,因为与电子信号处理相比,光学材料具有更宽的带宽。全光信号处理完全依赖于光与物质的非线性光学相互作用。这种相互作用导致新的光谱分量的出现和支持光束传播的介质的光学响应的修改。信息流的光谱中新频率的出现对于用于将信息信道从一个频带传送到另一个频带的波长转换是至关重要的。通过非线性相互作用改变光学介质的响应对于物理上分离的通道之间的信息流的光学切换是必要的;它几乎可以瞬间发生,比电切换快得多。另一个可以从非线性光学相互作用中受益的目标领域是量子信息。在量子通信网络中,人们可以安全地编码和传输信息。量子信息完全依赖于相关(纠缠)光子对的产生。这种光子对可以通过非线性光学相互作用产生,将一束光分解(下转换)成两束具有新频率的光。该研究计划的目标是开发纳米光子器件和纳米结构材料,旨在为光通信网络中的全光信号处理和量子信息领域产生高效的非线性光学相互作用。在光子材料和器件的非线性光学响应的增强实现的几种方法将被追求。第一种方法包括工程集成光学器件和光子纳米结构,以产生所需的增强。第二种方法是基于材料的;它依赖于纳米复合光学材料的非线性光学响应的物理学,纳米复合光学材料是两种或多种均匀成分的纳米级混合物。这种材料中单个晶粒的尺寸远小于光的波长,通过适当的剪裁可以实现静电光场的重分布,并在具有较高光学非线性的元件中实现局域化。结合这两种方法,预计将导致显着增强的光学非线性,开辟了新的有趣的物理和实际应用的路线。在用于全光信号处理的集成光学元件中实现增强的非线性光学响应,以及在生产集成量子光学网络中实现增强的非线性光学响应,是拟议研究计划的最终目标。
