Abstract

Quantum dots can modify the properties of the whispering gallery mode resonators (WGMRs) used in various potential applications. A deposition of a suitable nanomaterial for the surface functionalization of WGMRs allows for the achievement of high quality (Q) factors. Here, we show that the WGMR surface can be functionalized using quantum dots. We demonstrate that WGMRs covered with thin layers of HgS and PbS quantum dots are suitable for third-harmonic generation due to the high Q factor of the developed microresonators, thus significantly lowering the pumping power required for nonlinear optical interactions.

摘要

量子点可以改变用于各种潜在应用的回音壁模式谐振器（WGMRs）的特性。为WGMRs的表面功能化沉积合适的纳米材料能够实现高品质（Q）因子。在此，我们展示了可以使用量子点对WGMR表面进行功能化。我们证明，覆盖有HgS和PbS量子点薄层的WGMRs由于所开发的微谐振器具有高Q因子，适用于三次谐波产生，从而显著降低了非线性光学相互作用所需的泵浦功率。
