目的：研究一种适合广泛城域网部署的高性能掺铒波导放大器（edwa）的新方法。知识优势：这项工作的优点在于提出了一种基于gaas的EDWA，该EDWA结合了最近正在申请专利的发现：一种高质量的氧化InAlP铒主体材料，以及一种相对较新的非选择性湿热氧化技术实现的氧化平滑低损耗高折射率对比度脊波导，以及一种新颖的共振垂直腔内泵浦（VIP）方案，用于紧凑、单片集成谐振增强激发源。富磷酸InAlP天然氧化物提供了非常高的Er掺杂浓度，具有很长的荧光衰减寿命和非常宽的放大带。VIP激励提供高泵浦效率，均匀泵浦分布，多级泵浦噪声控制，简化封装，以及增加光子集成的可能性。更广泛的影响：该工作流程的影响来自组件成本的预期显著降低，这将使家庭、学校和医疗办公室的超高速多波长光通信可行，从而促进加速开发和采用带宽密集型应用，如数字视频、视频会议和跨多个平台的互联网通信，从而使社会受益。该研究还可能导致用于测距的人眼安全高能脉冲波导激光源和用于化学传感的宽带放大自发发射源。该项目通过将研究活动与本科工程专业的教学相结合，为教师参与者提供研究经验，并为未被充分代表的少数民族提供指导，促进教学、培训和学习。

Objective:This research targets a new approach for realizing high-performance erbium-doped waveguide amplifiers (EDWAs) for wavelength division multiplexed optical fiber communication networks at a cost suitable for widespread metropolitan area network deployment. Intellectual Merit:The merit of this effort lies in a proposed GaAs-based EDWA which incorporates recent patent-pending discoveries: a high quality oxidized InAlP erbium host material, and oxidation-smoothed low-loss high-index-contrast ridge waveguides enabled by a relatively new nonselective wet thermal oxidation technique, with a novel resonant vertical intra-cavity pumping (VIP) scheme for the compact, monolithic integration of a resonant-enhanced excitation source. The phosphate-rich InAlP native oxides afford very high Er doping concentrations with long fluorescence decay lifetimes and a very broad amplification band. VIP excitation offers high pumping efficiency, even pump distribution, multi-stage pumping for noise control, simplified packaging, and the possibility for increased photonic integration. Broader Impacts:The impacts of this work flow from the expected significant reductions in component cost which will benefit society by making ultra-high-speed multi-wavelength optical communications viable for the home, schools and medical offices, thus promoting the accelerated development and adoption of bandwidth-intensive applications such as digital video, video conferencing, and internet communications across multiple platforms. The research may also lead to eye-safe high-energy pulsed waveguide laser sources for range finding and broadband amplified spontaneous emission sources for chemical sensing. The project promotes teaching, training and learning through the integration of research activities with teaching of undergraduate engineering majors, Research Experience for Teachers participants, and the mentoring of underrepresented minorities.
