Abstract

Relaxation oscillation frequency is produced when a laser is operated in the low laser threshold current region. In this operation region, a semiconductor laser shows a smooth curve, where we can observe uncertainty into defining the onset of laser oscillation. Relaxation oscillations in the laser intensity can be seen as sidebands on both sides of the main laser line. In this context, a communication system by using a relaxation oscillation frequency as an information carrier is proposed in this paper. The experimental setup is based on operation principle of direct detection, where the obtained microwave signal at the output of a fast photodetector is located on C band and it is modulated with an analog NTSC TV signal.
