We demonstrate the high potential of cathodoluminescence (CL) spectroscopy for the study of point defects in the main classes of optical fibers: Telecom-grade, radiation-hardened, and radiation sensitive. Canonical samples, differently doped in their core (Ge, P, N) or their cladding (F), have been investigated by CL using electrons of energy ranging from 5 to 30 keV. Advantages and limitation of the CL tool are discussed on the basis of the obtained experimental results.

Abstract
We demonstrate the high potential of cathodoluminescence (CL) spectroscopy for the study of point defects in the main classes of optical fibers: Telecom-grade, radiation-hardened, and radiation sensitive. Canonical samples, differently doped in their core (Ge, P, N) or their cladding (F), have been investigated by CL using electrons of energy ranging from 5 to 30 keV. Advantages and limitation of the CL tool are discussed on the basis of the obtained experimental results.File in questo prodotto:
