Abstract:Diplomska naloga opisuje izdelavo zrcala znotraj enorodovnega optičnega vlakna. Predstavljeno je teoretično delovanje zrcal, orodja za izdelavo, izdelava ter praktični rezultati. Zrcalo je sestavljeno iz tankega zračnega mehurčka znotraj optičnega vlakna, izdelava pa temelji na jedkanju konca optičnega vlakna v fluorovodikovi kislini in varjenju pojedkanega dela z drugim ravno odrezanim optičnim vlaknom. Jedkanje je potekalo pri različnih časih ter pri konstantni temperaturi s čimer se je vplivalo na odbojnost zrcal. Varjenje je bilo nadzorovano s pomočjo sprotnih meritev refleksije ter transmisije s programskim okoljem LabVIEW. Z nadzorom jedkanja ter varjenja smo dosegli odbojnosti preko 8% pri izgubah manjših od 7%, zaradi česar so takšna zrcala primerna za izdelavo raznih optičnih senzorjev.

Title:MANUFACTURING OF MIRRORS INSIDE OPTICAL FIBERS
Abstract:Diploma describes manufacturing process of optical mirror within single mode optical fiber. Theoretical background of such mirrors is represented in this work together with manufacturing tools, manufacturing and experimental results. Mirror is constructed from thin air cavity within optical fiber, while manufacturing is based on etching of tip of optical fiber in hydro-fluoric acid and splicing of etched fiber with another flat cleaved optical fiber. Etching was conducted at different times and at constant temperature to effect on mirror’s reflectivity. Splicing process was controlled by simultaneous readings of reflectivity and transmittance of mirrors using program environment LabVIEW. Using controlled etching and splicing, reflectivity over 8% was achieved, with loses less than 7%. This is also a reason why these mirrors are suitable for construction of different optic sensors.
Keywords:Optical fiber, optical mirror, reflection, transmittance
