Abstract :
Summary form only given. A comprehensive theoretical model has been developed to describe amplification of picosecond optical pulses in mid IR SOAs. The investigations show that gain dispersion, short carrier relaxation time, and ultrafast nonlinear refraction have significant impact on the amplified pulse characteristics in the time and frequency domains. Calculations also indicate that gain dispersion can be enhanced by fast carrier relaxations, short pulse widths, and high pulse energies.
