Popis: | Simple expressions of modal self and cross transfer coefficients have been established in the case of an optical fibre connection with small defects. A complete theoretical study leads to exhibit special azimuthal properties for the LP1,n modes family which had not been noticed up to date. Experimental applications of these properties in techniques of modal metrology are used in order to evaluate the quality of multimode or monomode connectors by the precise determination of the transverse offset between two fibres. |
