Webbirefringence increases up to 2o. In the rest of the sample where the mechanical stress is lower, the birefringence remains less than 1o as shown in Figure 5. We can conclude from above that, as long as the beam passes through the central area, inhomogeneous and stress induced birefringence is less than 1o for a sample thickness of 10cm. WebA new method to amplify the photon-axion conversions in magnetic field is proposed using a buffer gas at a specific pressure. As a first result, new bounds for mass and coupling constant for purely laboratory experiments aiming to detect any hypothetical scalars and pseudo-scalars which can couple to photons were obtained at 95% confidence level, …

Lecture 3. Attiq Ahmed Optical Communication Single Mode Fibers The core size of single mode fibers is small. The core size (diameter) is typically around 8 to 10 micrometers. A fiber core of this size allows only the fundamental or lowest order mode to propagate. Single mode fibers propagate only one mode, because the core size …
The significance of the birefringence is that optical materials can be cut to impose specific changes in the polarization of incident beams. For example half-wave plates are cut to impose 180o (1 2 2! ()) phase shifts. When linearly polarized light travels in a birefringent crystal, the phase difference imposed on the two

We initially find a birefringence angle of β = 0.30 ° ± 0.11 ° (68% C.L.) for nearly full-sky data. The values of β decrease as we enlarge the Galactic mask, which can be interpreted as …
