Abstract :
A wavelength temperature-tunable DFB-LD module containing a wideband athermal birefringent filter for a wavelength monitor has been developed. The FSR and the thermal drift of the filter are measured to be 12.7 nm and 0.26 pm/°C, respectively. By temperature wavelength tuning, ten channel selection for 50 GHz spacing and stabilisation with locking accuracy of ±7 pm are also demonstrated
