我们开发了由KTaO 3单晶制成的固体浸没透镜。KTaO 3在405 nm波长处的折射率为2.382。使用KTaO 3作为固体浸没透镜的原材料，我们可以设计有效数值孔径为2.20。我们观察到一个150 GB的容量与130 nm的轨道间距和47.6 nm的位长度的眼模式。面密度为104.3 Gbit/in.2。
We developed solid immersion lenses made of a KTaO3 monocrystal. The refractive index of KTaO3 is 2.382 at a wavelength of 405 nm. Using KTaO3 as the raw material of a solid immersion lens, we could design an effective numerical aperture of 2.20. We observed an eye pattern of a 150 GB capacity with a 130 nm track pitch and a 47.6 nm bit length. The areal density is 104.3 Gbit/in.2.
