title: Micro-characterisation of erbium-doped fibers using a Raman confocal microscope.
abstract: We demonstrate the application of a Fluorescence Intensity Confocal Optical Microscopy technique to the determination of the relative erbium ion distribution in optical fibers. As well as being able to acquire two dimensional profiles of the relative erbium ion distribution, this method can also provide valuable information on a sub-micron level regarding physical and optogeometric parameters of the examined samples.
