Abstract :
A singular value decomposition (SVD) eigenvalue spectrum is employed to explore the deterministic nature of the complex time series from a modulated semiconductor laser. With this method, the signature of chaos can be quickly identified and the noise contamination ratio can also be estimated. Relations between the supplied modulation of laser diode and the noise level are illustrated. The connection between relative intensity noise and the noise floor in the SVD spectrum has also been clarified
