| Abstract | |
Photonic crystals are structures that present a spatial periodic profile of the dielectric constant and have been shown as a promising platform for the development of integrated photonic devices. In this work, the band structure of a periodic pattern fabricated using the Laser Induced Forward Transfer (LIFT) technique on a chalcogenide glass was analyzed from a theoretical point of view, as to explore the possibilities of using such structure as a photonic crystal. A photonic bandgap was found in the visible spectrum, between 582 and 639 nm for TM polarized light according to the periodic plan of the structure. Also, the behavior of the structure as a waveguide was analyzed through Finite-Difference Time-Domain method, and the guiding as a function of the quantity of elements on the periodic matrix was examined to find a starting point for possible practical applications.
