The knowledge of GaN sample optical properties were also investigated, resulting refractive index for the GaN layers were found to be nTE=2.279±0.001 and nTM = 2.316±0.001 and good temperatur stability. Optimization of the structure parameters and electrodes required for this structure was conducted accurately by theoretical tools using BPM methods. The results showed possibility to realize GaN based MZI for future optical modulator devices.Show less >
