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

这项小型企业创新研究（SBIR）第一阶段研究项目将为光栅外耦合表面发射（GSE）激光器创造一种相移不敏感、二维（2d）光子晶格外耦器的制造工艺。光子晶格结构在集成光子电路的实现中具有广阔的前景。本文提出的光子晶格横向移动纳米图是一种使耦合器（功率和场）对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，有必要降低制造这些结构的制造复杂性，从而实现快速和廉价的GSE激光器制造。结合边缘发射激光器（功率高、材料可靠、电压低、使用成熟）和垂直腔面发射激光器（成本低、晶圆级测试、封装简单、集成度高）的理想特性，该工作将在电信、信息处理和数据通信领域具有广泛的应用。更广泛的影响将是最终以极低的成本实现极高的数据速率（5gbps至160gbps），并消除将光纤部署到桌面和家庭的障碍，从而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.
