A large wavelength tuning range is demonstrated for a three-electrode distributed Bragg reflector (DBR) laser by applying both forward and reverse bias to the passive Bragg section. In the reverse direction the tuning towards longer wavelengths is mainly attributed to electrical heating. By also using the phase tuning section, all wavelengths within a range of 22.1 nm can be reached with a side-mode suppression better than 25 dB and with an output power exceeding 4.4 mW.<>
