Abstract :
This paper presents a systematic investigation on the exploitation of the modulation bandwidth enhancement that can be obtained using the photon-photon resonance (PPR) effects in distributed Bragg reflector (DBR) lasers with antireflection coating at the grating end facet. For the first time, to the best of our knowledge, a complete design procedure has been found that allows a precise positioning of the PPR frequency; such a procedure has been successfully validated both in small and large signal modulation regimes. Conditions for maximum bit rate transmission are also discussed and verified analyzing the eye diagrams obtained by numerical simulations.
