Paper Abstract

Modal performances of multimode optical passive components are measured by use of a selective excitation technique. Pure LPm 1 modes up to LP15 1 mode are generated in a Ti:Sapphire laser cavity and launched in the input fiber of the component under test. Power measurements and modal analysis are operated at the output. Azimuthal dependency of LP1 1 mode excitation coefficient is used in an accurate centering technique of monomode and multimode splices or connectors.
