Abstract
We studied Z-scan measurement to utilize it as a technique determining third order nonlinear optical coefficients in the photonic bandgap structure. The property of bandgap structured material, loss of transmittance by Bragg reflection, converts the phase change to intensity change or vice versa. It shows up as a result of exchange between closed- and open- aperture in Z-scan measurement near bandgap region. Through the numerical simulation based on the investigation of dispersion relation, it is obtained that the results of Z-scan measurement with closed- and open- aperture vary according to the frequency region. © 2005 Old City Publishing.
