| Abstract(in English) | A 4×25-Gb/s electroabsorption modulator integrated with a distributed feedback laser (EADFB laser) array monolithically integrated with a low-loss optical multiplexer (MUX) is developed for 100GbE transmitters. A cascaded Mach-Zehnder (MZ) filter, which has no intrinsic loss, is used as the MUX. The measured loss of fabricated MZ-MUX is 2 to 3dB, which is improved by 4dB compared with that of the conventional 1×4 multimode interference (MMI) MUX. The MZ-MUX is monolithically integrated with a four-EADFB-laser array and the output power of the chip is increased. With the folded layout, the size of the chip is similar to that of the conventional chip. The fabricated chip is packaged into a very compact TOSA. The system requirements are satisfied with semi-cooled operation, and very clear eye openings are obtained after 10-km single-mode-fiber (SMF) transmission. The adjustment of filter spectra by current injection is also shown, and fine tuning is possible with very low injection current. |
