我们首次成功地在非周期光学超晶格(AOS)晶体中实现了均匀增益的多波长转换。实验中的两个AOS器件是由单位块厚度为3.5微米的2857个晶块数值合成的，在50℃下，双波长倍频的基波波长分别为1540和1545 nm，三波长倍频的基波波长分别为1540,1545和1553 nm。我们的实验和模拟表明，AOS波长转换器的输出光谱对典型的制造误差相当不敏感。
We have demonstrated what is to our knowledge the first successful achievement of multiwavelength conversion in an aperiodic optical superlattice (AOS) lithium niobate crystal with equalized gain. The two AOS devices in our experiment, numerically synthesized from 2857 crystal blocks with a unit block thickness of 3.5 microm, have fundamental wavelengths of 1540 and 1545 nm for double-wavelength second-harmonic generation (SHG) and of 1540, 1545, and 1553 nm for triple-wavelength SHG at 50 degrees C. Our experiment and simulation show that the output spectrum of an AOS wavelength converter is fairly insensitive to typical fabrication errors.
