ABSTRACT
Pulses of 3–9 ps duration at wavelengths between 1.22 and 1.27 μm are amplified by a 1.3 μm InGaAsP traveling-wave optical amplifier. The gain decreases linearly with the output energy by up to 2.6 dB at the highest available energies. The output energy and peak power of the amplified pulses are as large as 4 pJ and 400 mW, respectively. It is shown that the gain compression can be described by treating the amplifier as a homogeneously broadened two-level system. No distortion of the pulse shape is observed after amplification.
