| Abstract(in English) | There are growing demands of smaller footprint digital coherent optical modulators for metro networks application. In this report one chip integrated digital coherent silicon optical modulator is assembled in a module with 4-channel driver amplifiers. PN junctions of phase-shifters are driven at carrier depletion mode by applying inverse bias voltage. E/O f_<3dB> response of 33-GHz is obtained with the phase shifters. Mode-field-convertors which expand mode-field-diameter nearly to 10-μm are applied to the modulator chip facets and butt-coupled to optical fibers. Passive insertion loss of lower than 15-dB for C-band and the power deviation of lower than 1-dB are obtained. Round-trip experiments are demonstrated for characterization of the module. Clear constellation diagram is obtained even after 1000-km transmission. |
