Summary: | We present a novel Dual DFB laser for high-speed direct modulation. The design comprises two identical quarter-wavelength 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 57.6GHz. Operation of these devices under large signal modulation at 56Gbps and 72Gbps is demonstrated. |
