We investigated sub-wavelength and leaky-mode resonant gratings made on fibre facets.
These gratings are used as polarization dependent low and high modal reflectance mirrors,
respectively. Modal reflectances of about 95% and polarization extinction ratios of
about 18 dB can be achieved in leaky-mode resonance gratings. Influence of grating
fabrication imperfections on modal reflectance is discussed
