摘要

本文报道了用飞秒激光直接写入和聚焦离子束铣削制备的片上铌酸锂(LN)微谐振器中瞬态相位匹配二次谐波的产生。我们在直径为~102 μm，厚度为~700 nm的LN微盘上证明了归一化转换效率为1.1×10-3/mW。

Efficient second harmonic generation in an on-chip high-Q crystalline microresonator fabricated by femtosecond laser

We report on transiently phase matched second harmonic generation in an on-chip lithium niobate (LN) microresonator fabricated by femtosecond laser direct writing followed by focused ion beam milling. We demonstrate a normalized conversion efficiency of 1.1×10-3/mW in the LN microdisk with a diameter of ~102 μm and a thickness of ~700 nm.
