The effect of two-wavelength oscillation for short-optical-pulse generation in laser diodes by sinusoidal current modulation has been investigated using a rate equation analysis. A high peak power and short pulse without a tail can be generated at the shorter wavelength λ2 with the help of carrier damping through carrier-photon conversion at the longer wavelength λ1. This can be obtained provided that the cw threshold current for λ1 is lower than that for λ2 and the gain g2 larger than g1 at the high carrier excitation levels that occur under the conditions of gain switching.
