Resumen o descripción
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.
