Polarization mode coupling in long single-mode fibres
In this paper we look at the polarization state evolution of light propagating in long, birefringent, singlemode fibres in the presence of mode coupling. We show first that there always exist two orthogonal linear input polarizations which lead to linear output polarization for monochromatic light. The applicability of the coupled power equations is discussed and it is shown that they cannot be...
متن کاملBackscattering Measurement of Bending - Induced Birefringence in Single Mode Fibres
core were investigated. It was shown from the measurement that the beat length was about L = 23 mm (birefringence B = 5 x 10") and the state of linear polarisation of the incident light beam was maintained up to 0-6 kg/cm of the concentrated force when the incident plane of polarisation was coincident with the major axis of the fibre. It was also shown that the degree and the plane of polarisat...
متن کاملSingle-mode coherent synchrotron radiation instability
The microwave instability driven by the coherent synchrotron radiation (CSR) has been previously studied [G. Stupakov, S. Heifets, Phys. Rev. ST Accel. Beams 5, 054402 (2002)] neglecting effect of the shielding caused by the finite beam pipe aperture. The growth rate of the instability is large and, at low bunch density, is dominated by the long wavelength modes. Such modes may be close to the ...
متن کاملArchitectural freeform structures from single curved panels
The problem of covering a freeform surface by single curved panels can be treated with the concept of semi-discrete surface representations, which constitute a link between smooth and discrete surfaces. A surface composed from developable strips (called a D-strip model) is the semi-discrete equivalent of a quad mesh with planar faces, or a conjugate parametrization of a smooth surface. Using re...
متن کاملRadiation Damage in Wls Fibres
Several types of WLS bres, candidates to be used in the TILECAL/ATLAS detector, were irradiated in a 60 Co source. Bicron, Kuraray and Pol.Hi.Tech bres were exposed to a total dose of 150 Krad. The degradation of light output was measured just after irradiation and followed during several days. The results are presented.
