该小型企业技术转让（STTR）第一阶段研究项目将开发一种可靠、高功率（1至10 W）、稳定、高效、单频的9 xx至10 xx nm范围内的表面发射半导体激光器。所提出的设备将具有高速（~ 40 Gbps），低啁啾调制在高功率下通过调整进入外耦合器光栅的光场的相位的能力。这种损耗耦合分布式反馈（DFB）/分布式布拉格反射器（DBR）相移调制（PSM）光栅外耦合表面发射（GSE）激光器的技术路线图需要开发量子线（QWR）板耦合光波导激光器（SCOWL）结构。这些建议的设备代表了一种创新的方法，以提高效率的中等功率，低相干源的高功率，相干源，可用于激光显示器，激光雷达或自由空间通信应用。与VCSEL和边发射半导体激光器不同，这种光栅稳定相移调制（PSM）光栅外耦合表面发射（GSE）激光器的技术路线图包括集成电子电路和信号处理能力。该器件包含两个主要创新：1）具有高可靠性的极高单频功率，以及2）高功率下的极高速调制。高功率是通过SCOWL概念实现的。开发这种设备的知识需要材料，光学，光栅，纳米结构，半导体加工，材料生长，热转移，高速电子，包装和系统方面的专业知识。提出的先进研究是一种创新的光子学和电子技术，在电信，信息处理，数据通信，光纤到企业和家庭，娱乐，仪器仪表和计算方面具有广泛的应用。1064 nm和920 nm单频、衍射极限高功率器件的一个非常重要的应用是倍频，以获得用于显示和存储应用的绿色（532 nm）和蓝色（460 nm）激光。

This Small Business Technology Transfer (STTR) Phase I research project will develop a reliable, high power (1 to 10 W), stable, efficient, single-frequency surface-emitting semiconductor laser in the 9xx to 10xx nm range. The proposed device will have the capability for high speed (~ 40 Gbps), low chirp modulation at high powers by adjusting the phase of the optical fields entering an outcoupler grating. The technology roadmap for this loss-coupled distributed feedback (DFB)/distributed Bragg reflector (DBR) Phase-Shift Modulated (PSM) Grating-outcoupled Surface-Emitting (GSE) laser requires developing a quantum wire (QWR) Slab Coupled Optical Waveguide Laser (SCOWL) structure. These proposed devices represent an innovative approach to improving the efficiency of moderate power, low coherent sources to high power, coherent sources that can be used for laser displays, lidar or free space communication applications. Unlike VCSELs and edge-emitting semiconductor lasers, the technology roadmap for this grating-stabilized Phase-Shift Modulated (PSM) Grating-outcoupled Surface-Emitting (GSE) laser includes integration of the electronic circuitry and signal processing capability. The proposed device contains two major innovations: 1) very high single-frequency power with high reliability, and 2) very high-speed modulation at high power. The high power is achieved with a SCOWL concept. The knowledge to develop such a device requires expertise in materials, optics, gratings, nanostructures, semiconductor processing, material growth, thermal transfer, high-speed electronics, packaging and systems. The advanced research proposed is an innovative photonics and electronics technology that has broad applications in telecommunications, information processing, data communications, fiber to the business and home, entertainment, instrumentation and computations. A very important application of 1064 nm and 920 nm single-frequency, diffraction-limited high power devices is frequency doubling to obtain green (532 nm) and blue (460nm) lasers for display and storage applications.
