The lasing wavelength of a tunable three-electrode distributed Bragg reflector (DBR) laser is stabilised while also suppressing mode hopping. Wavelength stabilisation at four different wavelengths was maintained during a laser temperature change from 15 to 30°C, and the temperature dependence of the wavelength was reduced to <0.007nm/K.
