STTR Phase I: Compact Semiconductor Ring Resonator Lasers

这项小型企业技术转移研究(STTR)第一阶段研究项目将开发超低损耗、弯曲几何形状的复合半导体光波导。它将研究在低成本、低阈值、高输出功率和单频可调的紧凑型单面激光器中实现紧凑型半导体光波导弯和环形谐振器以改进光管理的可行性。这将使深度刻蚀高折射率对比度脊形波导的侧壁得到均匀的氧化。该工艺同时减少了侧壁粗糙度，修复了腐蚀损伤，提供了出色的表面钝化，并创建了一种高限制结构，使激光能够在低损耗、紧密弯曲的波导中高效运行。这一努力将加快半导体光波导和谐振器中操纵和管理光子的新创新的商业化，并促进在局域网和城域环境中更快速和更广泛地部署高带宽光通信网络。此外，拟议的紧凑型环形谐振器技术将使波分复用光纤网络组件的高级集成成为可能，这些组件与当前最先进的技术水平不符，为城域和长途电信市场带来了高效率和高带宽全光路由的新概念。

This Small Business Technology Transfer Research (STTR) Phase I research project will develop ultra low-loss, curved geometry compound semiconductor optical waveguides. It will investigate the feasibility of realizing compact semiconductor optical waveguide bends and ring resonators for improved light management in low-cost compact single-facet lasers capable of low threshold, high output power, and tunable single-frequency operation. This will enable the uniform oxidation of sidewalls in deeply etched high-index-contrast ridge-waveguides. The process simultaneously reduces sidewall roughness, remediates etch damage, provides excellent surface passivation, and creates a high confinement structure enabling efficient laser operation within low-loss, tightly-curved waveguides.This effort will accelerate the commercialization of new innovations for manipulating and managing photons in semiconductor optical waveguides and resonators, and promote more rapid and widespread deployment of high-bandwidth optical communication networks in local and metro area settings. In addition, the proposed compact ring resonator technology will make possible advanced integration of components for wavelength division multiplexed fiber optic networks that are not practical with the current state-of-the-art, bringing new concepts for high efficiency and high bandwidth all-optical routing to both metro and long-haul telecommunications markets.
