Monolthically Integrated High-Performance WDM Lasers and Nanosecond Tunable Lasers Based on Ultra-Compact Wavelength MUX/DEMUX

单片集成高性能WDM激光器该集成系统方案集中于基于单片集成紧凑型衍射光栅技术的新型多通道波分复用(WDM)半导体激光器，用于波长复用的紧凑型衍射栅技术要小得多。在这个方案中，我们将使用光栅来实现一个集成的光子芯片，该芯片将许多可单独寻址的激光波长都多路复用到一个输出波导中。这种半导体激光器子系统被称为WDM激光器，是密集波分复用(DWDM)网络的重要关键器件。目前的密集波分复用多通道激光发射机是基于分立器件的，将阵列-波导-光栅(AWG)模块连接到多个分布式反馈(DFB)激光器模块，导致子系统尺寸约为16,000 mm2。我们将在不超过2-4mm2的芯片上实现WDM激光器，将4-8个可单独寻址的激光波长有效地多路复用到一根光纤输出中。拟议的工作将导致下一代通信和WDM光子器件集成技术的重大进步。下一代集成波分复用光子器件的实现将对美国S在光子技术领域的竞争力产生重大影响。拟议中的工作将对这些广泛的影响做出重大贡献。该协会是西北大学国家科学基金材料研究与工程中心的成员，曾邀请高中教师进行暑期研究。该协会也是西北光子通信与计算中心的成员。西北材料研究与工程中心和西北光子通信与计算中心都提供了合作、协调、传播和促进研究和教学活动的场所，这些活动通常涉及公众、少数族裔学生和高中生。

Monolithically Integrated High-Performance WDM LasersAbstractThis integrated system proposal focuses on novel multi-channel wavelength-division-multiplexed (WDM) semiconductor lasers based on a monolithically integrated compact diffraction grating technology for wavelength multiplexing that is substantially smaller. In this proposal, we will use the grating to realize an integrated photonic chip that has many individually addressable lasing wavelengths all multiplexed into a single output waveguide. Such semiconductor laser subsystems, called the "WDM lasers", are important key devices for dense WDM (DWDM) networks. Current DWDM multichannel laser transmitters are discrete-device based with array-waveguide-grating (AWG) module joined to multiple modules of distributed feedback (DFB) lasers, resulting in a subsystem size ~16,000mm2. We will realize WDM lasers on a chip no larger than 2-4mm2 with 4-8 individually addressable lasing wavelengths efficiently multiplexed into a single fiber output. The proposed works will lead to significant advancements in next-generation communication and WDM photonic device integration technology. The realization of next-generation integrated WDM photonic devices will have substantial impacts on U.S.'s competitiveness in photonic technology areas. The proposed works will contribute significantly to these broad impacts.
