C. Chicanne et al., Characterization of optogeometric parameters of optical fibers by near-field scanning probe microscopies, J OPT SOC B, 17(9), 2000, pp. 1473-1482
The combination of atomic-force and scanning-near-field optical microscopie
s is useful for characterizing the physical and optical parameters of optoe
lectronic devices. With a commercial atomic-force microscope adapted, to pe
rform scanning-near-field optical measurements, we succeed in determining c
ore diameters, localizing the erbium doping zone, and analyzing propagation
modes in erbium-doped and multimodal optical fibers. (C) 2000 Optical Soci
