G02B6/02319 - CPC Classification

Classification description:

Light guides; Optical fibres with cladding; Microstructured optical fibre; Plurality of longitudinal structures extending along optical fibre axis, e.g. holes characterised by core or core-cladding interface features

Sub-classes:

G02B6/02323 » {Core having lower refractive index than cladding, e.g. photonic band gap guiding} 34
G02B6/02333 » {Core having higher refractive index than cladding, e.g. solid core, effective index guiding} 169
G02B6/02338 » {Structured core, e.g. core contains more than one material, non-constant refractive index distribution in core, asymmetric or non-circular elements in core unit, multiple cores, insertions between core and clad} 183
