碩士 === 國立交通大學 === 應用數學系 === 87 === Electronic-controlled route to chaos in a laser diode is further improved by a feedback control technique. By introducing an extra feedback control term cS (t- ), chaotic light output can be achieved by tuning the parameter c without changing the input signal and the bias current. In chaotic region, the power spectra of the photon density shows a broad continuous component and indicates chaotic vibrations in the laser diode. This approach offers an external-controllable chaotic light source for possible digital communication and cryptographic applications.
