ObjectiveSemiconductor lasers are of great importance to modern communication because of the enormous bandwidth they provide in transmitting information over optical fibers. Quantum dot (QD) lasers (based on small clumps of material) haves significant advantages over the standard technology (which are quantum wells (QWs) based on thin layers of material), including much greater temperature-insensitivity and inherently low chip. However, QD-lasers have not been adopted into commercial laser transmitters largely because no holographically-fabricated, loss-free, single-mode QD-devices at the technologically-important wavelength ranges have yet been demonstrated. The objective is to demonstrate the fabrication of these devices with commercially-feasible techniques. Intellectual MeritBecause the work will be done in direct collaboration with Ortel-Emcore (a semiconductor laser company), successful fabrication of the devices will lead immediately to investigation of their adoption into telecommunications applications. With loss-free devices, the inherent performance and fundamental limits of single-mode QD lasers can be finally evaluated. This proposed mixed-growth method for single mode lasers will be an enabling technology for the widespread adoption of QD material into the telecommunications market. Broader ImpactsThe many advantages of QD material suggest applications where it would be superior to quantum well lasers. This technology will drive lower-cost, high-bandwidth optical communications links. The close industrial-academic collaboration, including seminars by Ortel scientists given at Binghamton, seminars by the PI at Ortel and local industries, and on-site work by a graduate student at Ortel-Emcore, are a valuable component to this project and will be excellent experience for the students involved.

目的半导体激光器对于现代通信非常重要，因为它们在通过光纤传输信息时提供了巨大的带宽。量子点 (QD) 激光器（基于小块材料）比标准技术（基于薄层材料的量子阱 (QW)）具有显着优势，包括更高的温度不敏感性和固有的低芯片。 然而，QD 激光器尚未被应用于商业激光发射器，主要是因为尚未在技术上重要的波长范围内演示全息制造、无损耗、单模 QD 器件。 目的是展示使用商业上可行的技术制造这些设备。 智力优点由于这项工作将与 Ortel-Emcore（一家半导体激光器公司）直接合作完成，因此设备的成功制造将立即导致对其在电信应用中的采用进行调查。 借助无损器件，可以最终评估单模 QD 激光器的固有性能和基本限制。这种针对单模激光器提出的混合生长方法将成为电信市场广泛采用量子点材料的一项使能技术。 更广泛的影响 QD 材料的许多优点表明它的应用优于量子阱激光器。 该技术将推动低成本、高带宽的光通信链路。 密切的产学合作，包括 Ortel 科学家在宾厄姆顿举办的研讨会、PI 在 Ortel 和当地行业举办的研讨会，以及 Ortel-Emcore 研究生的现场工作，是该项目的重要组成部分，并将成为该项目的重要组成部分。为参与的学生带来了极好的体验。
