On-Chip, Integrated, Diamond Raman Laser

本研究的目的是开发基于单晶金刚石的集成光子平台及其应用，以实现从可见光到中红外宽波长范围的片上光网络。这将通过将光学器件（波导、谐振器等）和系统直接制造成亚微米厚的单晶金刚石薄膜来实现。我们将探索实现这种薄金刚石薄膜的几种方法。该研究项目将把金刚石引入到适合集成、片上、光子学的材料家族中。特别是，金刚石的强三阶非线性及其优异的热性能将被用来展示低阈值、高输出功率的集成金刚石拉曼激光器，以及基于集成金刚石环谐振器的宽波长范围频率梳。这项工作将为金刚石光子学的发展及其在量子信息处理、灵敏磁强计、光电子学、生命科学、生化传感、气相光谱、精密测量、高频机械振荡器和开关等各个领域的应用奠定基础。该研究具有很强的教育成分，并将提供一个独特的机会，培养学生在跨学科领域的各个层次，结合材料科学，基础物理，设备和系统级集成。公众对钻石宝石的迷恋和熟悉将使更广泛的受众参与其中。为了实现这一目标，将在波士顿的科学博物馆以及当地的K-12学校进行公开讲座和演示。该研究与工业以及钻石制造和应用（例如石油工业）有很强的联系。国际旅行将与英国公司进行关键交流，英国公司将提供高质量的合成金刚石基材。PI还将与比利时的研究人员会面，并参加钻石研讨会。

The objective of this research is development of integrated photonic platform based on single-crystal diamond and its application for realization of on-chip optical networks that operate over wide wavelength range from visible to mid-infrared. This will be achieved by fabricating optical devices (waveguides, resonators, etc) and systems directly into sub-micron thick single crystal diamond films. Several approaches to realize such thin diamond films will be explored. The research program will introduce diamond into the family of materials suitable for integrated, on-chip, photonics. In particular, diamond's strong third order nonlinearity and its excellent thermal properties will be leveraged to demonstrate low-threshold, high-output power, integrated diamond Raman lasers, as well as wide wavelength range frequency combs based on integrated diamond ring resonators. This work will lay down foundations for the development of diamond photonics and its applications in diverse fields including quantum information processing, sensitive magnetometry, optoelectronics, life-sciences, bio-chemical sensing, gas spectroscopy, precision measurements, and high-frequency mechanical oscillators and switches. The research has strong educational components and will provide a unique opportunity to train students at all levels in interdisciplinary field that combines material science, fundamental physics, devices and system-level integration. Public fascination and familiarity with diamond gem-stones will enable engagement of wider audience. To achieve this, public lectures and presentation will be given at the Museum of Science in Boston as well as at local K-12 schools. The research has strong ties with industry and both diamond manufacturing and applications (e.g. oil industry). The international travel will enable key exchanges with UK firm which will provide high quality synthetic diamond substrates. The PI will also meet with researchers in Belgium and attend a diamond workshop.
