Abstract- A modulated holding beam shining a VCSEL can improve modulation bandwidth by adjusting the semiconductor laser’s relaxation oscillation frequency. The improved modulation characteristics are accompanied by reduced damping rate. By choosing correct parameters, dynamical behaviors of system and cavity soliton are changed. Different features of cavity soliton such as maximum amplified intensity and frequency fluctuations are observable.
Keywords: Holding Beam, Modulation, Semiconductor laser.
