摘要:

高次谐波产生是指产生多个光学谐波,是一种超越微扰区的非线性光学现象。最初在气体介质中观察到的HHG最近已在固态材料中得到证实。如何控制极端非线性光学现象是一个具有挑战性的课题。与原子气体相比,固态材料在控制电子结构和载流子注入方面具有优势。在这里,我们展示了通过调整电子结构和载流子注入使用单壁碳纳米管(SWCNT)的HHG的控制。我们揭示了一系列的电子结构从金属到半导体的单壁碳纳米管的高次谐波光谱的系统变化。我们证明了通过电解质门控调谐电子和空穴注入到半导体单壁碳纳米管中,谐波产生的增强或减少超过一个数量级。这些结果开辟了一种方法来控制HHG内的场效应晶体管器件的概念。

英文摘要:

High-harmonic generation (HHG), which is generation of multiple optical harmonic light, is an unconventional nonlinear optical phenomenon beyond perturbation regime. HHG, which was initially observed in gaseous media, has recently been demonstrated in solid state materials. How to control the extreme nonlinear optical phenomena is a challenging subject. Compared to atomic gases, solid state materials have advantages in controlling electronic structures and carrier injection. Here, we demonstrate control of HHG by tuning electronic structure and carrier injection using single-walled carbon nanotubes (SWCNTs). We reveal systematic changes in the high-harmonic spectra of SWCNTs with a series of electronic structures from a metal to a semiconductor. We demonstrate enhancement or reduction of harmonic generation by more than one order of magnitude by tuning electron and hole injection into the semiconductor SWCNTs through electrolyte gating. These results open a way to control HHG within the concept of field effect transistor devices.
