Abstract

We present a novel Dual DFB laser for high-speed direct modulation. The design comprises two identical quarter wavelengths shifted DFBs in mirrored configuration separated by a passive waveguide. This structure utilizes the effect of photon-photon resonance to increase the modulation bandwidth of 57.6 GHz. Operation of these devices under large signal modulation at 56 Gbps and 72 Gbps is demonstrated.
