The broader impact potential of this I-Corp project is the development of a compact chip technology for generating coherent lasers from visible to infrared. The proposed technology is designed to turn an inexpensive, limited performance laser diode into a top-of-the-line diode with a broad color range. The resulting product may be an affordable alternative to high-end laser products and extend laser emission wavelengths to a wide range of interest. In addition, the chip technology based on silicon nitride photonics may be produced by wafer-scale CMOS-compatible fabrication and may support laser light generation from 350 nm to 4500 nm, which would help solve existing scalability challenges in a variety of application fields. The proposed technology may provide a universal and scalable silicon photonics solution for integrated lasers for a variety of applications including quantum science, biochemical sensing, autonomous driving and LiDAR, and augmented/virtual reality.This I-Corps project is based on the development of a compact chip-integrated laser for generating coherent laser sources that can produce light from visible to infrared. The goal is to combine laser injection locking and optical parametric oscillation (OPO) based on a photonic crystal ring (PhCR). The proposed technology takes advantages of two nanophotonics technologies: on-chip OPO and high-quality PhCR, to solve the challenge of integrating chip laser with ultra-broad spectral coverage from visible to infrared. Lasers with such a wide range have not been proposed or demonstrated previously by existing technologies. The proposed chips may be produced in large scale, hence low-cost, by wafer scale CMOS compatible fabrication. In addition, the proposed technology may be compatible with other existing laser technologies, providing a versatile platform to generate high quality laser sources and a wider wavelength range. Such a device may significantly improve the ability of existing microcavities to enhance the interaction between light and matter and improve integrated commercial and research activities, particularly for integrated quantum science.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corp项目的更广泛的影响潜力是开发紧凑的芯片技术，该技术可从可见光到红外产生相干激光器。拟议的技术旨在将廉价，有限的性能激光二极管变成具有广泛色彩范围的顶级二极管。最终的产品可能是高端激光产品的负担得起的替代品，并将激光发射波长扩展到广泛的兴趣。此外，基于氮化硅光子学的芯片技术可以通过晶体尺度cmos兼容的制造产生，并可能支持从350 nm到4500 nm的激光发电，这将有助于解决各种应用领域中现有的可伸缩性挑战。 所提出的技术可以为集成激光器提供通用且可扩展的硅光子学解决方案，用于各种应用，包括量子科学，生化感应，自动驾驶和雷达，以及增强/虚拟现实。这个I-Corps项目基于用于生成CORENTEC COREDER COREDER COREDER cONERED CORVERED FRAMIFE FRIMED FRAMIFE FRAMIFE FRAING FRAING CORDECE cORESER的IP-CORPS项目。 目的是将激光注入锁定和基于光子晶体环（PHCR）的光学参数振荡（OPO）组合。 提出的技术具有两种纳米素技术技术的优势：片上OPO和高质量的PHCR，以解决将芯片激光与从可见光到红外线的超大型光谱覆盖范围相结合的挑战。现有技术先前尚未提出或证明具有如此广泛范围的激光器。 提出的芯片可以大规模生产，因此由晶圆量表CMOS兼容制造。此外，所提出的技术可能与其他现有激光技术兼容，该技术提供了一个多功能平台来生成高质量的激光源和更宽的波长范围。这种设备可能会大大提高现有微腔增强光与物质之间相互作用的能力，并改善综合商业和研究活动，尤其是对于综合量子科学而言。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的审查标准通过评估来进行评估的。
