We demonstrate a theoretical model of channel mismatch effect in a mode-locked laser based time-wavelength interleaved optical clock generation system. The channel mismatch effect includes clock timing mismatch, amplitude mismatch, and pulse shape mismatch. An explicit expression of this model is derived for 2-channel simple system and a numerical simulation of multiple-channel complicated system is carried out. In comparison with the experimental measurement, the feasibility of the theoretical model is verified for calibration and compensation of the channel mismatches.
