论文摘要
通过将钻石微球与飞秒摩擦式写入的散装块钻石波导整合在一起，实现了全钻石光子电路。近表面波导是通过利用II型制造方法来制造的，以实现应力诱导的波导。将在近红外区域运行的可调激光器的电气和横向磁光度光线注入到钻石波导中，当钻石波导与钻石微球耦合时，该光线显示出窃窃私语模式，间距为0.33 nm的间距，并通过仔细地进行了这些较高的质量，并在这些高品质因素上进行了进一步的属性。钻石微球和钻石波导在这种构型中，应该有可能在集成的钻石光子学中实现过滤，传感和非线性光学应用。
An all-diamond photonic circuit was implemented by integrating a diamond microsphere with a femtosecond-laser-written bulk diamond waveguide. The near surface waveguide was fabricated by exploiting the Type II fabrication method to achieve stress-induced waveguiding. Transverse electrically and transverse magnetically polarized light from a tunable laser operating in the near-infrared region was injected into the diamond waveguide, which when coupled to the diamond microsphere showed whispering-gallery modes with a spacing of 0.33 nm and high-quality factors of 105. By carefully engineering these high-quality factor resonances, and further exploiting the properties of existing nitrogen-vacancy centers in diamond microspheres and diamond waveguides in such configurations, it should be possible to realize filtering, sensing and nonlinear optical applications in integrated diamond photonics.
