利用聚焦离子束刻蚀技术，在三台4.44 THz法布里-珀罗量子级联激光器解理面间引入了周期分别为9.11、9.24、9.44个/splµ/m的一维光子晶格。在精确定义的波长分别为67.59、68.48、70.00/splµ/m处实现了单模激光。
Focused ion beam etching has been used to introduce one-dimensional photonic lattices, of periods 9.11, 9.24, 9.44 /spl mu/m, between the cleaved facets of three 4.44 THz Fabry-Perot quantum cascade lasers. Singlemode lasing has been achieved at precisely defined wavelengths of 67.59, 68.48, 70.00 /spl mu/m, respectively.
