\u00dcber das Projekt<\/strong><\/p>\n

\"\"<\/p>\n

Zurzeit arbeite ich an einem Projekt mit dem Titel \"Vektorwirbelstrahlen und ihre Streuung f\u00fcr Kommunikationsanwendungen\". In unserem Optiklabor entwickeln wir neue Instrumente und Techniken zur Erzeugung von Vektorwirbelstrahlen. Vor kurzem habe ich eine Technik vorgeschlagen, bei der ein Glan-Laser-Polarisator (GLP), eine q-Platte und ein polarisationsempfindlicher r\u00e4umlicher Lichtmodulator (SLM) einen Vektorwirbelstrahl erzeugen, der in der Mitte eine undefinierte Phase und ein ungleichm\u00e4\u00dfiges Polarisationsprofil aufweist. Wir haben diesen Strahl verwendet, um eine sichere Kommunikation zwischen zwei Enden herzustellen (die Daten werden sicher verschl\u00fcsselt) und die optischen Informationen zu verschl\u00fcsseln. Neben dem Vektor-Wirbelstrahl haben wir in unserem Labor auch perfekte optische Wirbelstrahlen (POV) mit einem SLM (der nur im Phasenmodus betrieben wird), einem Axikon und einer Linse (die die optische Fourier-Transformation von Bessel-Gau\u00df-Strahlen durchf\u00fchrt, um den POV-Strahl zu erzeugen) erzeugt. Au\u00dferdem haben wir diese Strahlen durch eine geschliffene Glasplatte (GGP) gestreut, woraufhin Speckle-Muster (ein feink\u00f6rniges, zuf\u00e4lliges Lichtmuster, das durch die Interferenz vieler gestreuter Wellenfronten aufgrund der Inhomogenit\u00e4ten auf der Oberfl\u00e4che eines GGP entsteht) erzeugt wurden. Dann haben wir die Korrelation (sowohl Auto- als auch Kreuzkorrelation) von zwei Speckle-Mustern genommen und diese Korrelation benutzt, um eine klassische Kommunikation herzustellen.\u00a0<\/span><\/p>\n

I work as a Forschung<\/a> fellow of physics in the project titled \u201cVector vortex beam and their scattering for communication application\u201d funded by Science and Engineering Research Board (SERB), Department of Science and Technology (DST), Govt.of India. <\/span><\/p>\n

Zuvor hatte ich zwei Projekte mit den Titeln \"Growth of ZnO thin film on Silicon and Glass substrate by Pulsed Laser Deposition technique\" (Wachstum von ZnO-D\u00fcnnschichten auf Silizium- und Glassubstraten durch gepulste Laserabscheidung) am Institute of physics, DAE, Govt. of India als Summer Student Visiting Program (SSVP) Fellow, finanziert vom Department of Atomic Energy (DAE), und \"Effect of Gd, Ca doping on structural, magnetic and transport studied of SrMnO<\/span>3<\/span> Perowskite\" an der Utkal-Universit\u00e4t. Au\u00dferdem habe ich die Goldmedaille des Kanzlers (Gouverneur von Odisha) f\u00fcr die beste Note in meinem Abschluss an der Utkal University erhalten und war Empf\u00e4nger vieler angesehener Stipendien, Stipendien und Auszeichnungen wie UGC Rank Holder Scholarship (2016-17), Institute of Mathematics and Application Scholarship (AIR-02), Khirgovind Merit Scholarship, Graduate Aptitude Test in Engineering (GATE), Joint Entrance Screening Test (JEST) usw. <\/span><\/p>\n

Ich bin Mitglied der American Physical Society (APS), der American Chemical Society (ACS), der Optical Society of America (OSA), der Asia Society of Researchers (ASR), des Institute of Corrosion und der Cognitive Science Society (CSS).<\/span><\/p>\n
