Results on long-period gratings /LPG/ written by a scanned focused beam of a CO2 laser in step-index fibers drawn at temperatures of 1880 and 1930 .sup.o.sup.C are reported. Transmission spectra of LPG fabricated repeatedly in one-week intervals in fiber regions which were 70 cm apart show to large changes of the residual stress occurring in the fiber after drawing. Results on the preparation of a new type of a fiber for LPG inscription with an inverted parabolic-index profile in the cladding are reported, too.
