G02B6/02176 - CPC Classification

Classification description:

Light guides; Optical fibres with cladding comprising gratings; Refractive index modulation gratings, e.g. Bragg gratings characterised by means for compensating environmentally induced changes due to temperature fluctuations

Sub-classes:

G02B6/0218 » {using mounting means, e.g. by using a combination of materials having different thermal expansion coefficients} 47
G02B6/02185 » {based on treating the fibre, e.g. post-manufacture treatment, thermal aging, annealing } 13
G02B6/0219 » {based on composition of fibre materials} 13
