Nonlinear Photonic Microstructures

这项建议涉及用于光波和光子学的纳米结构的研究。提出要研究的具体问题包括计算模拟、新的超辐射相干源、激光器和高频调制器在同一芯片上的集成，以及用于量子光学器件研究的电子束写入技术的初步研究。群传播技术将被应用于量子过程的计算，并将从量子井器件的计算开始，然后通过将该技术应用于双费曼图的计算，将该技术扩展到人工结构的非线性光学性质的计算。一种可能性是基于超辐射发射的相干发射器。这项工作将与日本IBM研究实验室的Tadashi Fukuzawa共同进行。已对行波GaAs光调制器进行了模拟，结果表明它有可能对40 GHz有响应。如果是这样的话，那么在单个单片结构中具有集成的激光调制器是有意义的。

This proposal relates to the investigation of nanostructures for use in lightwaves and photonics. The specific issues which are proposed for investigation include computational simulation, new super-radiant coherent sources, the integration of a laser and a high frequency modulator on the same chip, and the initial investigation of electron beam writing techniques for the investigation of quantum optical devices. The team propagation technique will be applied for the computation of quantum processes and will begin with the calculation with quantum well devices and then will be extended to a calculation of non-linear optical properties of artificial structures by applying this technique to a computation of double Feynman graphs. One possibility is a coherent emitter based upon super-radiant emission. This effort will be pursued jointly with Tadashi Fukuzawa, IBM Research Laboratory, Japan. Simulations have already been carried out for travelling wave GaAs modulators indicating that it is possible to have a response to 40 GHz. If this is so, then it is of interest to have an integrated laser-modulator within a single monolithic structure.
