Il progetto<\/strong><\/p>\n

\"\"<\/p>\n

Attualmente, sto lavorando a un progetto intitolato \"Fascio di vortici vettoriali e il loro scattering per applicazioni di comunicazione\". Nel nostro laboratorio di Ottica, stiamo escogitando nuovi strumenti e tecniche per generare raggi vettoriali. Pi\u00f9 recentemente, ho proposto una tecnica in cui l'uso di un polarizzatore laser glan (GLP), una piastra q e un modulatore di luce spaziale sensibile alla polarizzazione (SLM) genera un fascio vettoriale che ha una fase indefinita al centro e un profilo di polarizzazione non uniforme. Abbiamo usato questo fascio per stabilire una comunicazione sicura tra due estremit\u00e0 (i dati saranno criptati in modo sicuro) e codificato le informazioni ottiche. Oltre al fascio Vector vortex, abbiamo anche generato Perfect optical vortex (POV) fasci nel nostro laboratorio utilizzando un SLM (operando in modalit\u00e0 solo fase), un axicon e una lente (esegue la trasformazione ottica di Fourier di Bessel Gauss Beams per generare il fascio POV). Inoltre, abbiamo sparso questi fasci attraverso una piastra di vetro smerigliato (GGP) dopo di che sono stati generati i modelli speckle (un modello casuale granulare fine di luce che sono generati a causa dell'interferenza di molti fronti d'onda sparsi dalle disomogeneit\u00e0 presenti nella superficie di un GGP). Poi abbiamo preso la correlazione (correlazione automatica e incrociata) di due speckle pattern e abbiamo usato questa correlazione per stabilire la comunicazione classica.\u00a0<\/span><\/p>\n

I work as a ricerca<\/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

In precedenza, ho completato con successo due progetti intitolati \"Crescita di film sottili di ZnO su substrato di silicio e vetro con la tecnica della deposizione laser pulsata\" presso l'Istituto di fisica, DAE, Govt.of India come Summer Student Visiting Program (SSVP) Fellow finanziato dal Dipartimento dell'energia atomica (DAE) e \"Effetto del drogaggio di Gd, Ca sulla struttura, magnetico e trasporto studiato di SrMnO<\/span>3<\/span> Perovskite\" alla Utkal University. Oltre a questo, sono stato il vincitore della medaglia d'oro del cancelliere (governatore di Odisha) per aver ottenuto i voti pi\u00f9 alti nella mia laurea presso la Utkal University e anche destinatario di molte borse di studio prestigiose, borse di studio e premi come 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) ecc. <\/span><\/p>\n
