Abstract

Harmonic repetition frequency pulses of 500 GHZ, and subsequently 1.54 THz, were generated from a mode-locked laser diode with a distributed Bragg reflector (DBR) section and a fundamental frequency of 38 GHz. The structure of the device was simulated using a complex electric field rate equation simulator based on a previously developed photon density model with filter extension. The dynamics of the establishment and stabilization of mode-locking were investigated, and the ratio of the whole cavity length to DBR length was found to exert a significant influence on harmonic mode locking when the facet reflectivities on the absorber and DBR sides of the laser diode are less than 30%. These results were found to agree with previous experimental results.
