Abstract :
We present a 10-Gb/s LiNbO/sub 3/ Mach-Zehnder modulator that allows tuning of the chirp in a wide range (-0.7/spl divide/0.7) by applying just a dc voltage, while the radio-frequency section is single drive. The device shows uniform performances across the chirp tuning range. By tuning chirp value, transmission tests showed power penalty less than 2 dB for spans up to 2100 ps/nm.
