In this paper, we analyze the nonlinear optical parameter $\gamma$ estimated from experimental results of spectral broadening in ZnO channel waveguides. The effective area was calculated for waveguides of various dimensions and using the resulting data, the nonlinear optical parameter $\gamma$ was obtained analytically. We compare these values with those estimated from measurements, and found good agreement between them. We extended the analysis to calculate the optimal size for maximum nonlinearity and found that the fabricated waveguides were very close to the optimal size.
