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.

该集成的系统建议着重于新型的多通道波长 - 波长 - 多路复流（WDM）半导体激光器，基于单一集成的紧凑型光栅技术，用于波长多发性的波长。在此提案中，我们将使用光栅实现一个集成的光子芯片，该集成光子芯片具有许多单独的可寻址激光波长，为单个输出波导。这样的半导体激光子系统（称为“ WDM激光器”）是密度WDM（DWDM）网络的重要关键设备。当前的DWDM多通道激光发射器是离散设备，基于阵列 - 波导晶状体（AWG）模块连接到分布式反馈（DFB）激光器的多个模块，从而导致子系统大小〜16,000mm2。我们将在不超过2-4mm2的芯片上实现WDM激光器，其中4-8个单独寻址的激光波长有效地将其多样化为单个光纤输出。拟议的作品将导致下一代通信和WDM光子设备集成技术的重大进步。下一代综合的WDM光子设备的实现将对美国光子技术领域的竞争力产生重大影响。拟议的作品将对这些广泛的影响产生重大贡献。 PI是西北大学NSF材料研究与工程中心（MRSEC）的成员，并涉及高中教师进行夏季研究。 PI还是西北光子通信与计算中心（CPCC）的成员。 MRSEC和CPCC都为经常涉及一般公众，少数学生和高中生的研究和教学活动提供了合作，协调，传播和促进研究和教学活动的场所。
