摘要：

A DFB laser emitting at a wavelength around 940 nm in a single longitudinal mode up to an output power of 500 mW with a side mode suppression ratio greater than 50 dB is presented. More than 4 nm tuning range was reached by varying the current between 100 and 800mA. Up to a power of about 300mW, the lateral far field revealed stable fundamental mode operation.
