| Summary: | Erbium doped fiber amplifiers and lasers have a great impact on optical
communication due to their ideal advantages for the compensation of light
energy during transmission through the fiber optic systems. This has been
the focus of many research groups. Replacing the bottleneck electronic
amplifier by the optical amplifier, a great improvement is made for the optical
communication systems.
New configurations have been conceived and realized in this thesis. They
have shown a great enhancement in amplifier and laser performance
parameters. Several new configurations, for example double pass with filter
which also supports multiple wavelengths, have been demonstrated and
investigated.
The design and performance parameters of the new configurations are
thoroughly characterized, showing an improvement in gain, noise figure output power flatness efficiency and side mode suppression ratio.
Enhancement of results has been experimentally demonstrated, where a
higher gain (56dB) and flat output power (<0.7dB), a higher signal to noise
ratio (77dB) and a higher efficiency (22%) are demonstrated. |
