微米级波纹波导中准相位匹配高次谐波的产生

Quasi-phase-matched high harmonic generation in corrugated micrometer-scale waveguides

Anton Husakou

摘要:

对亚微米周期波纹波导的高次谐波产生进行了数值研究。在波纹附近的等离子体激元场增强允许使用低泵浦强度。同时,周期性放置的波纹导致准相位匹配和相应的高谐波效率的增加。对波导结构进行了优化,并利用(1+1)维数值模型分析了所得的光谱。

英文摘要:

The high harmonic generation in periodically corrugated submicrometer waveguides is studied numerically. Plasmonic field enhancement in the vicinity of the corrugations allows to use low pump intensities. Simultaneously, periodic placement of the corrugations leads to quasi-phase-matching and corresponding increase of the high harmonic efficiency. The optimization of waveguide geometry is performed, and the resulting spectra are analyzed by the means of (1+1)D numerical model.
