Abstract

We experimentally evidence optical van der Pol (VdP) waveforms based on the modulation of a laser diode with a simple autonomous VdP electronic circuit. Sinusoidal and relaxation optical oscillations are obtained. Furthermore, optical relaxation pulses are easily generated based on the nonlinearity of the laser diode. Important applications in research, engineering, and technology are discussed.
