Abstract(in English) We have fabricated a small optical trasnmitter module based on monolithically integrated light source, in which four 25G EADFB lasers and their optical MUX are monolithically integrated on one chip, for middle- and long-distance 100GbE. For EA modulators, InGaAlAs-based tensile-strained quantum wells are used for large extinction ratio and the supression of hole pile up effect. Also, a shallow-ridge waveguide buried in low-dielectric constant material (BCB) is employed for larger E/O bandwidth. For the MUX region, on the other hand, a deep-ridge wavegudie is used for its strong optical confinement and low radiation loss and a MMI coupler is used for the MUX for its short length and low wavelength sensitivity. Fabricated chip is packaged in specially designed module with the size of 12 mm×20 mm. By using the module, we demonstrate 10- and 40-km error-free transmission on single mode fiber under 100-Gbit/s operation at 40 degrees Celcius. These results indicate that the module is useful for future-generation transceiver for 1OOGbE.
