Chaotic Laser

How can we generate chaotic signal using laser in optisystem?

[Joshua Donald]

Hi Aadil,

We can create a chaotic signal using an ideal single mode laser driven by a dc bias generator. Open up the dc bias generator and change the mode from normal to sweep then go into the parameter sweep window and change the spread to Gaussian. I gave the Gaussian distribution a nominal value 0.3 and standard deviation 0.1. This essentially makes the bias generator output random values and which will randomly vary the center frequency of the laser.

Josh

Hi Josh,

Thanks for the reply. Please let me know one more thing how can we check the chaoticity of the generated chaotic signal? I mean is there any method in optisystem or algorithm in Matlab?
