Abstract :
Reported is the fabrication and investigation of surface reliefs on cleaved facets of optical fibres using nanoimprint lithography. The prepared structures are diffractive elements and arrays of holes with sub-wavelength feature sizes. The results obtained indicate that nanoimprint lithography affords opportunity to miniaturise optical devices at low fabrication costs, replacing free-space optical elements
