This Demonstration shows the phase space of a modulated semiconductor laser. The parameters are

N

, the normalized carrier density;

P

, the normalized photon density;

I

m

(mA), the amplitude of the modulation current; and

f

m

(GHz), the frequency of modulation. The system exhibits both chaotic and periodic oscillations as you vary the amplitude and frequency of modulation.
