Abstract :
Experimental results are reported for a coolerless wavelength division multiplex (WDM) source. Simple quadratic trends extracted from the laser tuning characteristics are used to stabilise the wavelength for 32, 100 GHz-spaced, channels. Wavelength accuracy of <0.1 nm was maintained over a temperature range of up to 50degC, limited by the lasers used in this work
