Abstract

Przedmiotem zgłoszenia jest układ i sposób ustawiania kąta obrotu źródła światła spolaryzowanego. W układzie, w osłonie (1) zamocowany jest kolimator (2) podłączony do światłowodu (3) połączonego ze splitterem (4). Układ charakteryzuje się tym, że po przeciwnej stronie splittera (4) przyłączone są drugi światłowód (5) i trzeci światłowód (6) z wytworzonymi w ich rdzeniach skośnymi siatkami Bragga (7, 8). Każdy z drugich końców drugiego światłowodu (5) i trzeciego światłowodu (6) podłączony jest do osobnego analizatora widma optycznego (9, 10), które połączone są z modułem obliczeniowym (11), który za pomocą przewodu sterującego (12) połączony jest z napędem (13), do którego z jednej strony zamocowane jest obrotowo źródło światła spolaryzowanego (14), zaś z drugiej strony napęd (13) zamocowany jest na nieruchomej podstawie (15), natomiast moduł obliczeniowy (11) wyposażony jest w wejście (16) zewnętrznego sterownika kąta obrotu, tudzież kąt obrotu siatek Bragga (7, 8) względem siebie wynosi od 15° do 30°.The subject of the application is a system and method for adjusting the rotation angle of a polarized light source. In the system, a collimator (2) is mounted in a housing (1) and is connected to an optical fiber (3) connected to a splitter (4). The system is characterized in that, on the opposite side of the splitter (4), a second optical fiber (5) and a third optical fiber (6) with oblique Bragg gratings (7, 8) produced in their cores are connected. Each of the second ends of the second optical fiber (5) and the third optical fiber (6) is connected to a separate optical spectrum analyzer (9, 10), which is connected to a calculation module (11), which is connected to a drive (13) via a control cable (12), to which a polarized light source (14) is rotatably mounted on one side, and on the other side the drive (13) is mounted on a fixed base (15), while the calculation module (11) is equipped with an input (16) of an external rotation angle controller, and the angle of rotation of the Bragg gratings (7, 8) relative to each other is from 15° to 30°.
