Paper Abstract

This paper describes the theory and experimentation of the amplification of optical signals by damping rate adjustment of Semiconductor Diode Lasers using the facet pumped optical modulation technique., It was found that the modulation damping rate of the probe laser depends on the relative position of the pump laser wavelength with respect to the Fabry Perot resonant wavelength of the probe laser. This effect is a result of the carrier induced index change. It is shown experimentally and theoretically that the effect on the damping rate can be both positive and negative. The positive effect results in a larger damping rate, therefore a decrease in the resonant peak height. The negative effect results in a smaller overall damping rate, therefore an increase in the resonant peak height. It is this increase in the resonant peak height that is of interest, it allows amplification of the modulation frequency of the optical signal near the resonant frequency of the probe laser.
