9224604 Yariv This project wil investigate the fundamental noise properties of semiconductor lasers. The need for narrow bandwidth and frequency stabilized semiconductor lasers in coherent lightwave communication networks is crucial. For multi-channel distribution systems it is important that the laser frequency will be known exactly. In addition narrow laser linewidth increases the S/N ratio and the network's channel capacity. Narrow linewidth lasers are also needed for microwave links, precision spectroscopy, time and frequency standards and many other important applications. This research is motivated with the view of a significant, orders of magnitude, reduction of the quantum limited phase noise and increased frequency stability of the semiconductor laser. Another prospect is amplitude noise squeezing below the standard quantum noise limit. These important problems will be pursed using the concept of a semiconductor laser with dispersive loss. This work will continue and expand unfunded, exploratory studies in our group. The early results from these preliminary studies are promising. A subcontract to Professor Shevy at the University of Miami will contribute to the work on frequency stabilization and linewidth reduction ***

9224604 Yariv本项目将研究半导体激光器的基本噪声特性。 在相干光波通信网络中，对窄带宽和频率稳定的半导体激光器的需求是至关重要的。 对于多通道分配系统，精确地知道激光频率是很重要的。 此外，窄激光线宽增加了信噪比和网络的信道容量。 窄线宽激光器还用于微波链路、精密光谱学、时间和频率标准以及许多其他重要应用。 本研究的动机与一个显着的，数量级，减少量子限制的相位噪声和增加的频率稳定性的半导体激光器的视图。 另一个前景是振幅噪声压缩到标准量子噪声极限以下。 这些重要的问题将使用具有色散损耗的半导体激光器的概念来解决。 这项工作将继续下去，并扩大我们小组的无资金支持的探索性研究。 这些初步研究的早期结果是有希望的。 致迈阿密大学的Shevy教授的一封信将有助于频率稳定和线宽减小的工作 *
