摘要：

We show that when more than two channels operate continuous-wave (CW) simultaneously in shared dispersive element wavelength-division-multiplexing (WDM) lasers, chi((3)) in the passive shared waveguide can cause spontaneous fluctuations in frequency and power. We propose the simple cure of making the shared waveguide extremely short. We obtain a value for the nonlinear-index coefficient of our InGaAsP waveguides of +0.9 x 10(-12) cm(2)/W.
