9221651 Potasek The understanding of solid state devices and their interaction with optical fiber components is of importance in both solid-state physics and communications. Electroabsorption modulators made with bulk III-V semiconductors or multiple quantum well (MQW) are becoming important devices for encoding information in high-speed lightwave systems. Important issues remain to be resolved regarding their operation at high optical power, their integration with single-frequency lasers, and the effect of chirp on long-distance, high-speed fiber transmission for conventional and soliton systems. A study of the dynamic effects of the saturation of modulators is important for future applications of these devices, since most applications require the devices to operate at both high speed and high optical intensity. Additionally, we plan to study the effects of high input intensity of the modulator chirp since, for the most applications in fiber optic communications systems, especially when erbium-doped optical fiber amplifiers are used, it is important that the modulator operate with low chirp. ***

9221651 Potasek了解固态器件及其与光纤元件的相互作用在固态物理和通信领域都很重要。 用体III-V族半导体或多量子阱（MQW）制成的电吸收调制器正成为高速光波系统中编码信息的重要器件。 关于它们在高光功率下的操作、它们与单频激光器的集成以及啁啾对常规和孤子系统的长距离高速光纤传输的影响，仍有重要问题有待解决。 调制器的饱和的动态效应的研究对于这些设备的未来应用是重要的，因为大多数应用要求设备在高速和高光强下操作。 此外，我们计划研究调制器啁啾的高输入强度的影响，因为对于光纤通信系统中的大多数应用，特别是当使用掺铒光纤放大器时，重要的是调制器以低啁啾工作。 ***
