| In this work we present an experimental and numerical study of the angular dependence of the reflective optical properties of two-dimensional photonic structures with square and hexagonal periodicity, built on a silicon substrate. The work is motivated largely by the need for a new alternative development in telecommunications technology that is purely photonic. The structures that have circular and square inclusions were manufactured with the technique of Focused Ion Beam (FIB). This manufacturing technique was easy to use and has advantages over other techniques; because the structure can be machined in several sessions and we may induce structural defects in the photonic structure. The numerical analysis of the reflective optical properties was through the technique known as Integral Equation Method, that has a great advantage compared to other methods; which only take into account a finite number of sampling points along the contours of the unit cell and inclusion, allowing fewer computational resources. The integral method allows studying both infinite and finite systems. For infinite systems the band structure is obtained and in the case of finite systems, the propagation of electromagnetic waves through the system. When performing the numerical simulations, prohibited bands were obtained by increasing the filling fraction of the square or hexagonal unit cell. Finally, we show the numerical analysis about the wave propagation through photonic structures with similar features to those machined. One of the results was that when considering inclusions in a dielectric plate, considerably improving optical reflectance. | |
