摘要

本研究探索了一种基于邻苯二甲酸铷(RbAP)分子晶体和可调滤光材料的新型太赫兹辐射源。RbAP晶格在太赫兹频率范围内的高质量振荡响应使得在多个频率同时产生窄带太赫兹辐射,具有高光谱亮度和峰值功率。单飞秒激光脉冲激发晶体。在生成的光谱线之间的切换是使用平面超材料实现的,其吸收线依赖于入射辐射的偏振。开发的光源允许发射谱线的动态调谐,这使得它比传统的窄带光源(如量子级联激光器)更通用和高效。

Multispectral Narrowband Terahertz Source Based on RbAP Molecular Crystal and a Tunable Metamaterial Filter

This study explores a new type of terahertz-radiation source based on a molecular crystal of rubidium acid phthalate (RbAP) and a tunable metamaterial that functions as a filter. The high-quality oscillatory response of the RbAP crystal lattice in the terahertz frequency range enables the generation of narrowband terahertz radiation at multiple frequencies simultaneously, with high spectral brightness and peak power. Single femtosecond laser pulses excite the crystal. Switching between the generated spectral lines is achieved using a planar metamaterial, the absorption lines of which depend on the incident radiation polarization. The developed source allows for dynamic tuning of the emission spectral line, which makes it more versatile and efficient than conventional narrowband sources, such as quantum cascade lasers.
