G02B6/2753 - CPC Classification

Classification description:

Light guides; Coupling light guides; Optical coupling means with polarisation selective and adjusting means characterised by their function or use, i.e. of the complete device

Sub-classes:

G02B6/276 » {Removing selected polarisation component of light, i.e. polarizers} 40
G02B6/2766 » {Manipulating the plane of polarisation from one input polarisation to another output polarisation, e.g. polarisation rotators, linear to circular polarisation converters} 210
G02B6/2773 » {Polarisation splitting or combining} 261
G02B6/278 » {Controlling polarisation mode dispersion [PMD], e.g. PMD compensation or emulation } 39
G02B6/2786 » {Reducing the polarisation degree, i.e. depolarisers, scramblers, unpolarised output} 30
G02B6/2793 » {Controlling polarisation dependent loss, e.g. polarisation insensitivity, reducing the change in polarisation degree of the output light even if the input polarisation state fluctuates} 67
