This paper describes a multichannel modulator consisting of EAMs, an arrayed waveguide grating, and semiconductor optical amplifiers. The modulator achieves 2.5-Gb/s operation and low optical and electrical crosstalk. For a solitary high-speed 50-/spl mu/m-long EAM buried with ruthenium-doped semiinsulating-InP, the extrapolated 3-dB-down electrical bandwidth is as large as 80 GHz. Small-signal E/O response with 3-dB-down electrical bandwidth of over 50 GHz is demonstrated.
