Abstract :
10-Gbit/s optical duobinary transmission over a 200-km single-mode fiber is demonstrated using a lossless InP n-p-i-n Mach-Zehnder modulator monolithically integrated with a semiconductor optical amplifier. The device gain exceeds 8 dB and the static extinction ratio is over 26 dB for a wavelength of 1550 nm. An error free operation was achieved with a power penalty of less than 5 dB at a low driving voltage of 2.8 Vpp for push-pull operation.
