Abstract :
Stable and fast 100 GHz-spaced 30-channel digital tuning operation with single longitudinal-mode oscillation in a monolithically integrated semiconductor diode laser has been achieved. It is experimentally demonstrated that the oscillation frequencies of the tunable laser were stabilised using the chirped ladder interferometric filter.
