Wavelength modulation or frequency chirp accompanies the power modulation of current modulated semiconductor diode lasers. Standard diode laser theory predicts that the laser gain and wavelength are clamped for modulation frequencies well below the relaxation oscillation frequency (except at frequencies so low that temperature modulation in the laser induces wavelength modulation). The wavelength clamping is not observed in experiments. The authors show that straight-forward analysis of the wave equation for laser waveguide can resolve this discrepancy.
