SBIR Phase I: Coarse Wavelength Division Multiplexing (CWDM) Full-Spectrum Clad-Pumped Chromium Doped Fiber Amplifier

该小型企业创新研究（SBIR）第一阶段项目将开发包层泵浦掺铬光纤放大器（CDFA）模块，该模块将为粗波分复用（CWDM）网络系统提供1270 nm至1610 nm的全光谱光放大。将传统玻璃光纤和半导体放大器无法提供的具有一定光谱增益的单晶转换为可与单模光纤组件集成的单晶。传统的大块晶体技术、当代光纤技术和先进的光纤激光器技术的这种新颖组合可能是破坏性的，并且可能导致许多发现和应用。如果成功，该项目的成果将不仅为当前的CWDM系统提供全频谱放大，而且还为超高容量宽带密集波分复用（DWDM）系统提供途径。此外，该平台技术还具有其他应用，例如用于测试和测量的可调谐激光器以及CWDM转发器。

This Small Business Innovation Research (SBIR) Phase I project will develop a cladpumped Chromium doped fiber amplifier (CDFA) module that will provide full-spectrum optical amplification ranging from 1270 nm to 1610 nm for coarse wavelength division multiplexing (CWDM) network systems. A single crystal with certain spectral gain that traditional glass fibers and semiconductor amplifiers cannot offer is transformed to be integrateable with single-mode fiber-optic components. This novel combination of conventional bulk crystal technology, contemporary fiber optics technology, and advanced fiber laser technology may be disruptive and may result in many discoveries and applications. If successful the outcome of this project would not only provide full-spectrum amplification for current CWDM systems, but also provide the path to ultra-high capacity wideband dense wavelength division multiplexing (DWDM) systems. In addition, this platform technology has other applications such as tunable lasers for test and measurement, and CWDM transponders.
