9527241 Stegeman We will explore radical new opportunities for the application of spatial solitons to information manipulation in networks. Our ultimate goal will be to implement a hybrid, all-optical/electronic, reconfigurable NxN routing switch. Using a totally new concept will optically write bright spatial solitons which act as " guiding: channels between any two points on opposite sides of a self-focusing nonlinear material. Either TDM or WDM signals can be routed by these non-diffracting channels to interconnect abitary input and output signal paths. Furthermore, by controlling electro-optically the input soliton wavefront tilt, angular scanning of soliton channels ( and signal paths) in space will be demonstrated for connecting different inputs to different outputs on demand, i.e. a reconfigurable NxN interconnect. We will investigate the spurious deflection of spatial solitons by collisions in planar waveguides of A1GaAs and bis-paratoluene sulfonate (PTS). In fact, we have already characterized the nonlinear properties of A1GaAs waveguides, demonstrated all-optical switching devices and excited spatial solitons. Therefore these waveguides provide an excellent testbed for the new concepts involved. In parallel (with a student salary from a recent AASERT award from BMDO) we will investigate the feasibility of exciting spatial solitons in PTS which we have also recently characterized. PTS is important because it has the largest know nonresonant nonlinearity and its implementation into waveguides will lead to low-power spatial soliton generation, and ultimately interconnects. This work will be done in collaboration with Wagner at the University of Colorado Boulder. ***

9527241 Stegeman我们将探索空间孤子在网络信息操纵中的应用的新机会。 我们的最终目标将是实现一个混合的，全光/电，可重构的NxN路由交换机。 使用一个全新的概念将光学写入明亮的空间孤子，作为“引导：通道之间的任何两个点对两侧的自聚焦非线性材料。 TDM或WDM信号都可以通过这些无衍射通道进行路由，以互连任意的输入和输出信号路径。 此外，通过电光控制输入孤子波前倾斜，空间中的孤子信道（和信号路径）的角扫描将被证明用于根据需要将不同的输入连接到不同的输出，即可重构的NxN互连。 本文研究了AlGaAs和双对甲苯磺酸盐（PTS）平板波导中空间孤子碰撞引起的寄生偏转。 事实上，我们已经表征了A1 GaAs波导的非线性特性，演示了全光开关器件和激发的空间孤子。 因此，这些波导为所涉及的新概念提供了一个很好的试验平台。 与此同时（从最近的AASERT奖从BMDO的学生工资），我们将调查的可行性，激发空间孤子的PTS，我们最近也特点。 PTS是重要的，因为它具有最大的已知非共振非线性，其实施到波导将导致低功率空间孤子的产生，并最终互连。 这项工作将与科罗拉多博尔德大学的瓦格纳合作完成。 ***
