Semiconductor optical amplifiers will be important components in future optical communication and photonic switching systems. In this proposal, an experimental study of the potential of using both Fabry- Perot and traveling-wave laser amplifiers for enlarging the bandwidth of present fiber optic systems is proposed. In particular, this is a study of the problem of crosstalk, gain saturation, sensitivity and fidelity of both Fabry-Perot and traveling-wave laser amplifiers for the amplification of ultra high data rates intensity modulated wavelength multiplexed signals. In collaboration with Harry Diamond Laboratories, the principal investigator also proposes to fabricate waveguides and to optimize the optical coupling efficiency of bistable diode laser amplifiers in an out-of-plane addressing configuration by using 45o-angle mirrors and gratings fabricated with a focused ion beam. These technical objectives complement this work on photonic switching devices and, at the same time, support and enhance similar thrusts of the Harry Diamond Laboratories optoelectronic program. In addition, he proposes to use the technique of in-situ ellipsometry for monitoring the deposition of anti-reflection coatings on the facets of a commercially available diode laser. This will ensure the reproducible making of high-quality traveling-wave laser amplifiers.

半导体光放大器将是未来光学通信和光子开关系统中的重要组件。 在此提案中，提出了对使用Fabry-Perot和行进波激光放大器的潜力进行的实验研究，以扩大当前光纤系统的带宽。 特别是，这是对Fabry-Perot和行进波激光放大器的串扰，增益饱和度，灵敏度和忠诚度的研究，用于扩增超高数据速率强度调制波长多路复用信号。 与哈里·戴蒙德（Harry Diamond）实验室合作，首席研究员还建议制造波导，并在平面外的配置中优化双二极管激光放大器的光学耦合效率，并通过使用45o-angle镜子和用焦点构造的聚焦离子束来解决配置。 这些技术目标补充了光子开关设备上的这项工作，同时支持并增强了Harry Diamond Laboratories光电计划的类似推力。 此外，他建议使用原位椭圆法的技术来监测市售二极管激光器相的抗反射涂层的沉积。 这将确保可重现高质量的旅行波激光放大器。
