Kızılötesi dalgaboylarında mikrokürelerden gökkuşağı tarafından yükseltilmiş elastik gauss ışını saçılması

Microspheres are utilized for various applications in optoelectronics owing to their highquality factor cavity resonances that are called morphology dependent resonances (MDR?s) orwhispering gallery modes (WGM?s). Among these applications are biodetectors, ultrafinesensors, rotation sensors and wavelength division multiplexing components such asmicrolasers, optical couplers, optical filters, modulators, and channel droppers. In this work,we calculate the intensity of elastic scattering of an electromagnetic wave from amicrosphere for transverse electric and transverse magnetic polarizations. Calculations areperformed for Gaussian beams. We specifically calculate the rainbow enhanced elasticscattering intensity for Gaussian beams by using the localization principle and GeneralizedLorenz Mie Theory. Three spectral ranges are studied : Near-infrared (1530 nm to 1570 nm),mid-infrared (10.4 µm to 10.8 µm) and far-infrared (95 µm to 100 µm). In each of the spectralranges, we used microspheres having different refractive indices of 2, 1.4142, 1.236, and1.15. The maximum elastic scattering efficiencies at near infrared, mid-infrared and far-infrared ranges are calculated to be 11%, 8%, and 7%, respectively, provided that appropriateimpact parameters are used. Potential materials are found to be lithium fluoride (m = 1.4142@ 1550 nm), silicon monoxide (m = 2 @ 10 µm), lithium niobate (m = 1.236 @ 10 µm), leadtelluride ( m = 2 @ 100 µm), potassium chloride (m = 1.4142 @ 100 µm) and lead selenide (m = 1.15 @ 100 µm). These materials are transparent at the quoted spectral bands and areamenable to optoelectronic device applications.Keywords: Scattering analysis, optical properties, material properties, material selectionAdvisor: Prof. Dr. Ali Serpengüzel Date:Director of institute: Prof. Dr. Süleyman Özekici Date:
