ABSTRACT: There
is a constant growth in the demand of data information transmission capacity,
that is, more and more people send data, voice, video signals, among others,
through communications networks. Due to the above there is great interest in
improving network devices, such as optical amplifiers, which must cover a large
bandwidth and generate greater gain than those currently available. For this
reason in this work a computational simulation for a Quasi-system was carried
out three energy levels of Erbium and Ytterbium varying their concentrations
and proving that they are optimal candidates in a zinc phosphate matrix as this
type of glass contains properties such as, high transparency, low melting
point, high thermal stability, high gain density due to high solubility, low
refractive index and low dispersion, which makes them optimal as signal amplifiers.
The results confirm that by increasing the doping of the Erbium ion the gain of
the amplifier decreases, contrary to the Ytterbium ion that by increasing the
doping the gain of the amplifier increases.
