Fast wavelength switching with a tunable duplex integrated light source is reported. The device comprises two distributed Bragg reflector lasers, two electroabsorption optical switches, a Y- shaped waveguide coupler, and an electroabsorption modulator. Using the device, the wavelength of a 10Gbit/s NRZ-modulated optical signal can be switched without bit loss.
