One of the goals of optical fiber communication system design and development is the realization of the full 25 THz bandwidth capability of this transmission medium. One approach currently being pursued is to transmit a large number of spectral channels at high modulation rates within the gain profile of doped optical fiber amplifiers. Therefore in order for new device technologies to be acceptable they must be characterized with high spectral resolution probes (0.10-0.20 nm; 10-25 GHz at 1550 nm) over relatively large spectral bandwidths (C-Band: 1528-1561 nm; L-Band: 1561-1620 nm). One approach to accomplishing this task is to use a tunable laser source to probe the device to measure its spectral properties over a range of wavelengths. The polarization of the incident beam can also be changed to examine the sensitivity to polarization variations that may occur in a length of fiber. The source output can also serve as a continuous wave optical source that can then be modulated with an external modulator to examine the performance of a modulator at different wavelengths. In this regard a tunable laser source is an extremely versatile tool for investigating many different aspects of high performance fiber optic devices and systems.In addition to using a tunable laser source for research purposes it also is a very useful instrument for education purposes. It can be used in laboratory experiments that evaluate devices found in modern fiber optic communications systems such as fiber Bragg gratings, spectral gain variation of optical amplifiers, and amplifier gain equalization techniques. In addition it can be used to train both undergraduate and graduate students in DWDM device characterization techniques.The purpose of this proposal is a request for a tunable laser diode with a spectral resolution of 0.02 rim and a tuning range from 1510-1580 nm. This source will provide our lab with the capability to investigate the performance of devices and materials for wavelength selective operations in fiber optic communications systems. it will also allow us to significantly improve the quality and relevance of laboratory experiments that we can offer in our classes on fiber optics and undergraduate and graduate research projects. A source of this type is currently not available for our research and educational facilities and is a significant obstacle to our efforts. The importance of acquiring an instrument of this type is underscored by the commitment from the University of Arizona to cost share one-third of the cost of the laser.

光纤通信系统设计和开发的目标之一是实现这种传输介质的全25 THz带宽能力。目前所追求的一种方法是在掺杂光纤放大器的增益分布内以高调制速率传输大量光谱信道。因此，为了使新的设备技术是可接受的，它们必须在相对大的光谱带宽（C波段：1528-1561 nm; L波段：1561-1620 nm）上用高光谱分辨率探头（0.10-0.20 nm; 1550 nm处10-25 GHz）表征。完成此任务的一种方法是使用可调谐激光源来探测设备，以测量其在波长范围内的光谱特性。也可以改变入射光束的偏振，以检查对可能发生在一段光纤中的偏振变化的灵敏度。光源输出也可以用作连续波光源，然后可以用外部调制器调制，以检查调制器在不同波长下的性能。在这方面，可调谐激光源是一种极其通用的工具，可用于研究高性能光纤设备和系统的许多不同方面。除了将可调谐激光源用于研究目的外，它也是一种非常有用的教育仪器。它可用于实验室实验，评估现代光纤通信系统中发现的器件，如光纤布拉格光栅、光放大器的光谱增益变化和放大器增益均衡技术。此外，它可以用来培训本科生和研究生在DWDM设备的表征technology.The目的的建议是一个可调谐激光二极管的光谱分辨率为0.02 rim和调谐范围从1510-1580 nm的要求。该源将为我们的实验室提供研究光纤通信系统中波长选择操作的器件和材料的性能的能力。它还将使我们能够显着提高实验室实验的质量和相关性，我们可以在我们的类光纤和本科生和研究生的研究项目提供。我们的研究和教育设施目前没有这种来源，这是我们努力的一个重大障碍。亚利桑那大学承诺分担激光器三分之一的费用，这突出了获得这种仪器的重要性。
