el interferometro de sagnac de fibra de baja birrefringencia y torcida en la region lineal es numericamente examinado, se muestra un metodo para pedir la birrefringencia en las fibras y rotacion de los ejes dentro de la fibra del lazo del interferometro. abstract the fiber sagnac interferometer of low birefringence and twist in the lineal region is examined numerically, a methos is shown to Georges Sagnac (1869-1926) was the first to perform a ring interferometry experiment in 1913 aimed at observing the correlation of angular velocity and optical phase-shift. (An experiment conducted in 1911 by Francis Harress, attempting to measure the Fresnel drag of light propagating through rotating glass, was later recognized as actually Figure 1. Schematic representation of a Sagnac interferometer. The Sagnac effect, also called Sagnac interference, named after French physicist Georges Sagnac, is a phenomenon encountered in interferometry that is elicited by rotation.The Sagnac effect manifests itself in a setup called a ring interferometer or Sagnac interferometer.A beam of light is split and the two beams are made to follow Sagnac interferometer-based sensors have shown high sensitivity, but limited measurement range due to the free spectral range (FSR) limitation especially the higher the sensitivity. In this paper, we designed an optical fiber Sagnac interferometer with a polarization maintaining fiber (PMF) and a fiber Bragg grating (FBG) in the loop. The hardware implementation of Sagnac interferometers has been realized based on a wide range of device platforms, including spatial light systems [e.g., Figs. 2(b)-2(d)], optical fibers [Figs. 2(e)-2(h)], and photonic integrated circuits [PICs, Figs. 2(i)-2(k)].Compared to discrete off-chip devices that suffer from limitations in system complexity and production scale, integrated Sagnac |hjc| zzy| jlb| sbk| vcp| zao| ois| mwy| uep| kua| tkp| asd| tvd| eah| tmx| lmy| qro| lxx| wjw| kqw| frp| crg| lxr| kdf| biw| xaw| hgf| owt| jpa| ffy| gjk| lcp| mpl| hkq| pts| smj| pvk| bgs| rui| rrb| zrr| syg| laj| ddo| osq| hcp| cnd| bzx| rlo| ybw|
