Designing of omni-directional high reflectors by using one-dimensional modified hybrid Fibonacci/Cantor band-gap structures at optical telecommunication wavelength band

摘要

By studying the reflection spectra of one-dimensional modified hybrid quasi-periodic Fibonacci/Cantor structures at the optical telecommunication frequency band for any incident simulator and for both parallel (P) and orthogonal (S) polarizations, reflection bands covering the three wavelengths of telecommunication were obtained, where the propagation of light is forbidden in this region for all incident angles and for S polarization. The broad extension of the stop band explains that strong light localization occurs in this region. The modification law of the stacks was introduced by applying the following rule , where x _j is the position of the beginning of the jth layer, y _j is the position of the beginning of the jth layer after modification and where k represents the coefficient defining the modification degree. The reflection spectra are determined by using a theoretical model based on the transfer matrix method (TMM).View full textDownload full textKeywordshybrid quasi-periodic photonic structure, omni-directional high reflector, modified photonic systemRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09500340903545289
