G02B6/02109 - CPC Classification

Classification description:

Light guides; Optical fibres with cladding comprising gratings; Refractive index modulation gratings, e.g. Bragg gratings characterised by their structure, wavelength response characterised by the core or cladding or coating, e.g. materials, radial refractive index profiles, cladding shape having polarization sensitive features, e.g. reduced photo-induced birefringence
