Very low wavelength chirp (static < 0.07 GHz/mA and dynamic < 0.09 GHz/mA) was measured for a directly-modulated fibre grating laser with an angled facet semiconductor chip and a short fibre grating. Low-penalty transmission at 2.5 Gbit/s over 312 km of standard singlemode fibre has been demonstrated using this low-chirp device.
