Abstract :
A simple wavelength control circuit is demonstrated that maintains single-longitudinal-mode operation of coupled-cavity semiconductor lasers over wide ranges of temperature. Photodetection properties of the lasing system itself are used for generating the discriminating signal for the feedback loop. No external optical elements like photodetectors or spectrometers are required.
