Abstract :
We have developed a widely tunable laser source that uses triple ring resonators with narrow spectral linewidth. A spectral linewidth of less than 100 kHz is obtained for all wavelength channels across C-band. This laser achieved a high fiber output power of ~16 dBm and a high side-mode-suppression ratio of > 45 dB.
