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 12mmx20mm. 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 100GbE. |
