This 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.

该集成系统方案集中于基于用于波长复用的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，该技术实质上更小。在这个提议中，我们将使用光栅来实现集成光子芯片，该集成光子芯片具有多个可单独寻址的激光波长，所有这些波长都被复用到单个输出波导中。这种半导体激光器子系统，称为“WDM激光器”，是密集WDM（DWDM）网络的重要关键设备。目前的DWDM多通道激光发射机是基于分立器件的，其中阵列波导光栅（AWG）模块连接到多个分布反馈（DFB）激光器模块，导致子系统尺寸约为16，000 mm 2。我们将在不大于2- 4 mm 2的芯片上实现WDM激光器，其中4-8个可单独寻址的激光波长有效地复用到单个光纤输出中。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WDM光子器件的实现将对美国的光通信系统产生重大影响。在光子技术领域的竞争力。拟议的工程将大大有助于这些广泛的影响。PI是西北大学NSF材料研究与工程中心（MRSEC）的成员，并参与了高中教师的暑期研究。PI也是西北光子通信和计算中心（CPCC）的成员。MRSEC和CPCC都提供合作，协调，传播和促进研究和教学活动的场所，这些活动通常涉及普通公众，少数民族学生和高中生。
