Abstract :
100 mum-stripe, 2 mm-long, DFB diode lasers with narrow spectral widths of 2.3 Aring FWHM were achieved at a CW power of 5 W. The centre wavelength was locked at the Bragg condition and shifts at a rate of 0.065 nm K-1. 1 mm-long DFB laser showed a record high 53% wallplug efficiency for grating-stabilised semiconductor lasers at 25degC heatsink temperature and 2 W CW output power
