Abstract : This effort investigates the mechanism and applications of microwave-frequency intensity oscillation of laser diodes with short external cavity. Future Air Force analog fiber optic links will require RF bandwidths of 10-60 GHz with dynamic range greater than 120 dB. Systems are investigated here which could deliver these specifications in a compact, light weight and low power approach. A theoretical simulation is presented using a nonlinear dynamic point of view. Analyses show that Hopf bifurcation is responsible for the occurrence of the high-frequency intensity oscillations that can be used for communication links. An experimental investigation into frequency deviation, amplitude fluctuations and phase noise was also conducted.
