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.

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在实现从可见光到中红外的宽波长范围内运行的片上光网络中的应用。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。将探索几种实现这种金刚石薄膜的方法。该研究计划将把金刚石引入适合集成、片上、光子学的材料系列中。特别是，将利用金刚石强大的三阶非线性及其优异的热性能来演示低阈值、高输出功率、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、灵敏磁力测量、光电子学、生命科学、生化传感、气体光谱、精密测量以及高频机械振荡器和开关等领域的应用奠定基础。该研究具有强大的教育成分，将为在结合材料科学、基础物理、设备和系统级集成的跨学科领域培训各级学生提供独特的机会。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，将在波士顿科学博物馆以及当地的 K-12 学校举办公开讲座和演示。该研究与工业以及钻石制造和应用（例如石油工业）有着密切的联系。国际旅行将使与提供高质量人造金刚石基材的英国公司进行重要交流。 PI 还将与比利时的研究人员会面并参加钻石研讨会。
