SBIR Phase I: Nano-Patterned, Phase Shift Insensitive, 2-Dimensional Photonic Lattice Outcoupler for Grating Surface Emitting Lasers

这一小型企业创新研究(SBIR)第一阶段研究项目将创建一种用于光栅出耦合表面发射(GSE)激光器的相移不敏感、二维(2-D)光子晶格外耦器的制造工艺。光子晶格结构为集成光子电路的实现提供了广阔的前景。这里提出的光子晶格横向移动纳米图形是一种使耦合器(功率和场)与它必须耦合的光信号的相位不变的方法。然而，为了充分实现这一潜力，必须降低制造这些结构的复杂性，从而可以实现快速且廉价的GSE激光器的制造。结合边缘发射激光器(高功率、材料可靠、低电压、使用可靠)和垂直腔面发射激光器(低成本、晶片级测试、封装简单、集成能力高)的特点，这项工作将在电信、信息处理和数据通信中具有广泛的应用前景。更广泛的影响将是最终以非常低的成本实现非常高的数据速率(5 Gbps到160 Gbps)，并消除将光纤部署到桌面和家庭的障碍，实现商业和娱乐的超高BW连接。

This Small Business Innovation Research (SBIR) Phase I research project will create a manufacturing process for phase-shift insensitive, 2-dimensional (2-D) photonic lattice outcoupler for grating-outcoupled surface-emitting (GSE) lasers. Photonic lattice structures hold great promise for the realization of integrated photonic circuits. The photonic lattice laterally shifted nanopattern proposed here is an approach to make the coupler (power and field) invariant to the phase of the optical signal it must couple. However, for this potential to be fully realized, it is necessary to reduce the complexity of fabrication of making these structures, such that rapid and inexpensive manufacturing of GSE lasers can be achieved. Combining the desirable traits of both edge emitting lasers (high power, reliable material, low voltage, use of proven) and vertical cavity surface-emitting lasers (low cost, wafer level testing, simple packaging, high integration ability), this work will have broad applications in telecommunications, information processing and data communications. A broader impact will be eventual realization of very high data rates (5 Gbps up to 160 Gbps) at very low cost, and the elimination of barriers to deploying fiber to the desktop and to the home, enabling ultra high BW connections for business and entertainment.
