摘要:

片上光学微谐振器的设计和制造的最新进展极大地扩展了它们在光子学中的应用,使计量、通信和片上激光器成为可能。这些应用的设计需要对色散、带宽和高光学品质因数进行精细控制。由于设计策略在很大程度上限于横截面几何形状的分析调整,因此这些品质因数的协同设计仍然是一个重大的技术挑战。在这里,我们表明,光子逆设计促进和扩展的功能,片上微谐振器,理论和实验证明灵活的色散工程,品质因数超过200万的绝缘体上硅平台与单模操作,和选择性的波长带操作。

英文摘要:

Recent advances in the design and fabrication of on-chip optical microresonators has greatly expanded their applications in photonics, enabling metrology, communications, and on-chip lasers. Designs for these applications require fine control of dispersion, bandwidth and high optical quality factors. Co-engineering these figures of merit remains a significant technological challenge due to design strategies being largely limited to analytical tuning of cross-sectional geometry. Here, we show that photonic inverse-design facilitates and expands the functionality of on-chip microresonators; theoretically and experimentally demonstrating flexible dispersion engineering, quality factor beyond 2 million on the silicon-on-insulator platform with single mode operation, and selective wavelength-band operation.
