Ultrafast 1.55 Micron Quantum Dot Mode-Locked Lasers

提出了一个研究计划，以了解科学和推进半导体锁模激光器的技术，并减少脉冲宽度和增加输出功率超过一个数量级。该研究包括单片锁模激光器的静态和动态色散的研究，以及通过在器件中加入量子点有源区来减少或消除动态色散和使用静态色散元件来补偿自然静态色散来最小化它们。实验和分析研究的目标将是生产在宽光谱带宽上具有最小色散的器件，以实现脉冲宽度短至100 fs，平均功率高达20 mW，脉冲重复率高达40 GHz。该计划将由南加州大学Merit研究计划招募的一名女研究生和两名本科生助理进行。博士生将承担该计划的所有分析和实验工作，包括材料生长，器件制造和测试以及器件物理的详细建模。这些学生将确保进行的跨学科研究和培训由少数人和年轻人接受，他们在职业生涯的早期就接触到了设备固有的跨学科性质。最后，所学的知识将被纳入构成南加州大学光子学教育计划核心的两门光子学课程。

A program of research is proposed to understand the science and advance the technology of semiconductor modelocked lasers and to reduce the pulse width and increase the output power by more than one order of magnitude. The research comprises the study of static and dynamic dispersion in monolithic mode locked lasers as well as their minimization by the incorporation of quantum dot active regions in the devices to reduce or eliminate the dynamic dispersion and the use of static dispersive elements to compensate the natural static dispersion. The objective of the experimental and analytical studies will be to produce devices with minimal dispersion over a broad spectral bandwidth to achieve pulse widths as short as 100 fs, average powers as high as 20 mW and pulse repetition rates as high as 40 GHz.The program will be carried by a woman graduate student and two undergraduate assistants who are recruited from the USC Merit research program. The PhD student will undertake all of the analytical and experimental work of the program including materials growth, device fabrication and testing as well as detailed modeling of the device physics. These students will insure that the interdisciplinary research and training that is carried out is received by a minority person and by people young enough are exposed early in their careers to the inherent interdisciplinary nature of device. Finally, the knowledge learned will be included in two courses on photonics that form the core of the photonics education program at USC.
