Abstract :
We have investigated bistability of a DBR laser using side-mode injection. Flip-flop operation is demonstrated with low input switching power. The threshold switching power is reduced significantly by decreasing the wavelength detuning from the side-mode. Thus, an optical memory based on a DBR laser can be easily addressed by controlling the input signal wavelength.
