Abstract :
Self-assembled nanostructures with two characteristic periods, sub-wavelength along polarization and close to wavelength along propagation direction, are revealed in silica glass after femtosecond laser writing. The phenomenon is interpreted in terms of exciton-polariton crystal formation.
