Dynamic wavelength stabilization of an AlGaAs diode laser has been demonstrated. The diode laser is butt coupled to a stripe-loaded optical waveguide which contains a Bragg reflecting grating. The laser is pulsed with 50-ns-long, 25% duty cycle, 100% modulation depth pulses and the waveguide output is observed to remain at single wavelengths over a peak current range of 120-160 mA and 15 °C temperature variations.
