Coupled-cavity mode locking of a KCI:TI color-center laser has been achieved with passive waveguides fabricated in the AlGaAs material system. The ultrafast refractive nonlinearity at the half-band gap is exploited by the laser to produce pulses as short as 230 fs at operating wavelengths of ∼1520 nm.
