The paper presents the calculation of the planar optical
amplifier gain and the optimal length of the active optical amplifier
waveguide doped with Bi-Ge radiation complexes compared to an
optical amplifier with active doping with ions Er, Yb. At present are
using optical amplifiers for the high-capacity optical communication
systems in the narrow spectral region of 1530–1560 nm, determined
by the gain bandwidth of erbium-doped fiber amplifiers (EDFA) or
erbium-doped optical planar amplifiers (EDPA) realized as active
planar waveguides in the optical integrated circuits
technique. However, it is possible increase wavelength region up to
1610 nm, where optical losses of telecommunication fibers are less
than 0.3 dB per km, if appropriate amplifiers are available. In this
regard, the development of novel optical amplifiers operating in this
spectral region have of great importance. The paper summarizes the
results measurement and calculation of the transmission
characteristics of the amplification of the new active silica glass
structures and possibilities novel optical amplifiers for extension of
the bandwidth from 1530 to 1610 nm doped by bismuth- erbium
ions.
