Abstract :
We have demonstrated a simple wavelength-tunable integrated laser/modulator based on an InGaAsP strained active layer that enables continuous wavelength tuning of several nm with a single electrical control. A 2.5-Gbit/s 600-km normal fiber transmission was demonstrated with a wavelength tuning range of 200 GHz.
