Abstract: A compact full C-band external cavity wavelength tunable laser is proposed. The cavity contains a fixed etalon and makes use of a liquid-crystal-based tunable mirror. The measurement results show a tuning range of 35 nm with fiber coupled power of more than 15 dBm. The sidemode suppression ratio is higher than 50 dB over the whole range and the relative intensity noise is below -148 dB/Hz. The linewidth is in worst case 700 kHz.
