Abstract :
Gain stabilization has been achieved for semiconductor optical amplifiers through the use of a feedback control system which dynamically adjusts the amplifier drive current. Measured results show that amplifier gain variations created by changes in input signal polarization, wavelength and amplifier chip temperature have been reduced to 0.1 dB.
