A chaotic light generator device comprises laser structures (10,12) integrated on a common substrate (14). Each laser structure comprises a ridge (100,120) of light amplifying material that forms a waveguide extending between at least partly reflective surfaces (19). Each laser structure (10,12) comprises an injection electrode (102,122) for injecting electric current into the ridge (100,120) of light amplifying material. The laser structures (10,12) are mutually coupled for exchanging light. A current feed circuit (20,22) is coupled to the electrodes (102,122) and configured to apply mutually different current densities to the electrodes of the laser structures (10,12).
Choosing different lengths of the laser structures (10,12) and suitable current densities, chaotic light emission is achieved resulting in ultrashort laser pulses suitable for telecommunication applications. |
