Abstract :
We fabricated wavelength tunable laser diodes with Si photonic wire waveguide ring resonators as an external optical cavity. Less than 100 kHz narrow spectral linewidth was obtained with small footprint. Our wavelength tunable laser diode shows sufficient good performance for practical use in digital coherent optical transmission systems.
