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通信和光子交换系统的重要组成部分。 在该提案中，提出了使用法布里-珀罗放大器和行波激光放大器来扩大现有光纤系统带宽的潜力的实验研究。 特别是，这是对用于放大超高数据速率强度调制波长复用信号的法布里-珀罗放大器和行波激光放大器的串扰、增益饱和、灵敏度和保真度问题的研究。 首席研究员还与 Harry Diamond 实验室合作，提出通过使用 45o 角反射镜和聚焦离子束制造的光栅来制造波导，并优化平面外寻址配置中双稳态二极管激光放大器的光学耦合效率。 这些技术目标补充了光子开关器件方面的工作，同时支持和增强了哈利戴蒙德实验室光电计划的类似目标。 此外，他建议使用原位椭圆测量技术来监测市售二极管激光器面上减反射涂层的沉积情况。 这将确保高质量行波激光放大器的可重复制造。
