Abstract

Recent progress in electroabsorption modulator integrated distributed feedback (EADFB) lasers for high-speed data communications is described. For 100 Gigabit Ethernet (100GbE) applications, an ultrasmall optical semiconductor chip, in which four 1.3-μm 25-Gbit/s EADFB lasers and an optical multiplexer are monolithically integrated, has been developed for future 100GbE transceivers. This small chip enables the overall transmitter size and the number of optical components to be significantly reduced compared with conventional 100GbE transmitters. Furthermore, for future beyond-100-Gbit/s applications, we have developed 50-Gbit/s EADFB lasers and obtained very clear eye openings even after 40-km transmission.
