This Small Business Innovation Research Phase I project aims to develop a super broadband, 1.27~1.61 micron, Amplified Spontaneous Emission (ASE) light source for spectral test instrumentation. This innovation has significant market potential. Spectral measurement is necessary for all components used in the Wavelength Division Multiplexing (WDM) optical communication systems, in particular, for next-generation WDM networking systems using the newest optical fiber: zero-water-peak fiber, which eliminated the water absorption peak at 1.4 micron and extended the low-loss transmission window to 1.27~1.61 micron continuously for the first time. This innovation would offer a solution for the need of a super broadband gain medium that traditional gain media such as fiber lasers and diode lasers cannot offer. This innovation has significant intellectual merit. A disruptive technology would be used in this project. The device module would be composed of a specialty crystal fiber with designed single-mode confinement structure, directly pumped by diode laser. The overall package would be compact with its output power coupled into a standard single-mode fiber at a target of 100 mW. The novel transition and linkage between conventional bulk-crystal optics and contemporary fiber optics would inspire many publications and patents. This project would strengthen the U. S. technology leadership in WDM and would have a multiplier effect to the overall optical-telecommunications industry. Moreover, this innovation would establish a technology platform for a series of super broadband amplification products, which would be among the key components enabling the next-generation optical communications using super broadband zero-water-peak fiber.

该小型企业创新研究一期项目旨在开发用于光谱测试仪器的超宽带，1.27~1.61微米放大自发辐射（ASE）光源。 这项创新具有巨大的市场潜力。光谱测量是波分复用（WDM）光通信系统中所有元件的必需，尤其是采用最新光纤的下一代WDM网络系统：零水峰光纤，它首次消除了1.4微米处的水吸收峰，并将低损耗传输窗口连续扩展到1.27~1.61微米。这一创新将为诸如光纤激光器和二极管激光器等传统增益介质所不能提供的超宽带增益介质的需求提供解决方案。 这一创新具有重大的智力价值。一项颠覆性的技术将被用于这个项目。器件模块由一根特殊的晶体光纤组成，光纤具有设计的单模限制结构，由二极管激光器直接泵浦。整个封装将是紧凑的，其输出功率以100 mW的目标耦合到标准单模光纤中。传统的大块晶体光学和当代光纤光学之间的新的过渡和联系将激发许多出版物和专利。该项目将加强美国。S.在WDM技术的领导地位，并将有一个乘数效应，整个光通信行业。此外，这项创新将为一系列超宽带放大产品建立技术平台，这将是使用超宽带零水峰光纤实现下一代光通信的关键组件之一。
