Engineering and controlling photon states in photonic crystal fiber

abstracteccs - 0802109 m。目的：为了推进量子光学信息技术领域的发展，本项目探索在小芯光纤中通过自发四波混频产生纠缠光子对的方法。这提供了优势，包括产生的光子与低损耗光纤传输的模式匹配良好。这项工作将由俄勒冈大学的Raymer小组、贝尔实验室的McKinstrie小组和加州大学圣地亚哥分校的Radic小组合作进行。智力优势：他们将在高度非线性光纤和光子晶体光纤中使用参数相互作用来实现几个基本功能：1)在控制光谱相关或纠缠程度的光纤中产生对光子；2)在保持光谱或纠缠特性的情况下实现光纤中光子和模式的量子态的频率转换（平移）；3)在光纤中产生模式的幅值纠缠场；4)通过非线性布拉格散射实现不同载流子频率信号的线性耦合。更广泛的影响：光信号的波长敏捷性在现代通信系统中起着重要作用。量子频率转换至少有两个用途：1)实现量子信号的波分复用，包括用于量子密码密钥分发的信号；2)提供一种方法，在多个信道之间操纵纠缠光子，用于量子计算。该项目将量子光学学家与其他机构的光学器件科学家聚集在一起，为博士生提供了与不同科学家互动的机会，并从他们的设施和专业知识中受益。非线性光学提供了极好的机会，将研究与科学教育相结合。

AbstractECCS-0802109M. Raymer, University of Oregon EugeneObjective: To advance the field of quantum-optical information technology, this program explores methods for creating entangled photons pairs by spontaneous four-wave mixing in small-core optical fibers. This offers advantages, including creating photons that are well mode matched for low-loss fiber transmission. The work will be carried out by a collaboration of the Raymer group at the University of Oregon, the McKinstrie group at Bell Labs, and the Radic group at UC San Diego. Intellectual Merit: They will use parametric interactions in highly nonlinear fibers and photonic-crystal fiber to enable several basic capabilities: 1) pair-photon generation in fiber with controlled degree of spectral correlation or entanglement, 2) frequency conversion (translation) of quantum states of photons and modes in fiber while maintaining spectral or entanglement properties, 3) generation of amplitude-entangled fields of modes in fiber, and 4) linear coupling of signals at different carrier frequencies through nonlinear Bragg scattering.Broader impacts: Wavelength agility of optical signals plays an important role in modern communication systems. Quantum frequency conversion would have at least two uses: 1) to enable wavelength-division multiplexing of quantum signals, including those used for quantum cryptographic key distribution, and 2) to provide a means to manipulate entangled photons between many channels for the purpose of quantum computation. The project brings together quantum opticians with optical device scientists at other institutions, providing the opportunity for PhD students to spend time interacting with diverse scientists and benefiting from their facilities and expertise. Nonlinear optics offers excellent opportunities to integrate research with science education.
