ObjectiveWe propose to design and build a suite of multichannel nonlinear-optical signal-processing devices (2R regenerator for phase-shift-keying transmission formats, switch/gate, and wavelength converter) based on nonlinear-optical loop mirror (NOLM), in which the key and novel component enabling the simultaneous processing of multiple wavelength-division-multiplexing (WDM) channels is a group-delay-managed (GDM) nonlinear medium. Such a GDM-medium differs from conventional dispersion-managed media in that its dispersion map is not only spatially, but also spectrally periodic, which eliminates nonlinear inter-channel interaction by ensuring large dispersive walk-off among different WDM channels, while preserving the integrity of each channel's pulses. The project consists of three key efforts: a) development and testing of multi-functional multichannel nonlinear-optical signal processor based on GDM-medium-enabled NOLM; b) design/fabrication of ultra-low-loss GDM-medium implementing novel multiport periodic-group-delay-device on a chip; c) theoretical modeling of GDM-based NOLM. Intellectual meritThe proposed first realization of devices that utilize large intra-channel optical nonlinearity while suppressing the inter-channel nonlinearity will overturn the accepted paradigms of all-optical processing, making transformative impact on optical communications, networking, and computing.Broader impactThis project will dramatically reduce complexity and cost of nonlinear-optical signal processing systems, expediting the roll-out of all-optical networking and increasing the bandwidth availability. The reduced, compared to electronic processing, power consumption will contribute to better environment. The compatibility of this approach with silicon and chalcogenide-glass waveguides makes it potentially beneficial for board-to-board and chip-to-chip networking. This funding will support three graduate students who will get synergetic experience in optical communications systems, device fabrication, and applied mathematics.

目的设计和制作一套基于非线性光学环镜(NOLM)的多通道非线性光信号处理装置(2R相移键控传输格式再生器、开关/门和波长转换器)，其中实现多个波分复用(WDM)通道同时处理的关键和新颖部件是群延迟管理(GDM)非线性介质。这种GDM介质与传统的色散管理介质的不同之处在于，它的色散映射不仅在空间上是周期性的，而且在频谱上是周期性的，这通过确保不同WDM信道之间的大色散走离，同时保持每个信道的脉冲的完整性来消除非线性信道间的相互作用。该项目包括三个关键工作：a)基于GDM介质使能NOLM的多功能多通道非线性光信号处理器的开发和测试；b)实现新型多端口周期群延时器件的超低损耗GDM介质的设计/制造；c)基于GDM的NOLM的理论建模。智能优点首次提出的利用通道内光学非线性同时抑制通道间非线性的器件将颠覆公认的全光处理范例，对光通信、网络和计算产生变革性影响该项目将极大地降低非线性光信号处理系统的复杂性和成本，加快全光网络的铺设并提高带宽利用率。与电子加工相比，功耗的降低将有助于更好的环境。这种方法与硅和硫化物玻璃波导的兼容性使其对板到板和芯片到芯片联网具有潜在的好处。这笔资金将支持三名研究生，他们将在光通信系统、设备制造和应用数学方面获得协同经验。
