GOALI: University-Industrial Collaborative Research on LiNbOIntegrated Optical Laser/Modulator Arrays for WDM Systems

波分复用/交换网络具有极大地增加现有光纤系统的灵活性和信息承载能力的潜力。 通道数和通道密度目前受到二极管激光器的中心频率稳定性的限制。 工艺变化和载流子引起的折射率变化可以在器件之间产生高达+7 nm的波长变化。 作为一个由Er：LiNbO_3波导分布反馈激光器阵列与行波调制器集成组成的系统。这种材料系统不具有半导体激光器的加工或电子可变性。 因此，激光频率应完全由光栅光刻的再现性决定。 我们建议威斯康星州大学（UW）和联合技术光子学公司（UTP）共同努力生产该设备。我们希望展示功能齐全的包装设备。 该计划的结果将大大提高对这些有源波导器件的理解，以及开发商业LiNbO 3产品的深入知识和经验。 ***

9521228 McCaughan Wavelength division multiplex/switching networks have the potential for greatly augmenting the flexibility and information carrying capacity of present fiber optic systems. Channel number and channel density are currently limited by the center-frequency stability of diode lasers. Processing variations and carrier-induced index changes can produce up to +7 nm wavelength variations among devices. As an system composed of an array of Er: LiNbO3 waveguide distributed feedback lasers integrated with traveling-wave modulators. This material system possesses none of the processing or electronic variabilities of semiconductor lasers. Lasing frequencies should, therefore, be determined solely by the reproducibility of the grating lithography. We propose a joint effort between the University of Wisconsin (UW) and United Technologies Photonics (UTP) to produce the device. We expect to demonstrate fully functional and packaged devices. The results of this program will be a greatly enhanced understanding of these active waveguide devices, and the in-depth knowledge and experience to develop commercial LiNbO3 products. ***
