Abstract :
The fabrication of sub-micron photonic structures beyond diffraction limit is demonstrated by means of tightly focused laser pulses. 25 mm long periodic structure with a pitch size of 260 nm is experimentally produced. Detailed numerical modelling is performed to establish mechanisms of such inscription.
