Abstract :
Polarization dependent periodic nanostructures consisting of long-range arrayed planes of modification, < 20 nm thick and separated by ∼240 ± 25 nm, are created in fused silica through femtosecond laser irradiation. The periodicity is revealed by ultrahigh spatial resolution chemical etching combined with atomic force microscopy.
