Optical field enhancement factor of Silicon and indium phosphide nano-cavities

Abstract

Nano cavities based on silicon and indium phosphide materials have been compared<br />in this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.
