Investigation of Thermal Dispersion and Thermally-Induced Birefringence on High-Power Double Clad Yb:Glass Fiber Laser
In this work the effects of heat generation on the modes of Yb:Glass double clad fiber laser were investigated. The thermal dispersion and thermally-induced birefringence were considered when the gain medium becomes an anisotropic medium. The results showed considerable modifications of laser modes profiles, in particular for transfer magnetic (TM) and transfer electric (TE) modes which their p...
متن کاملInfluence of birefringence dispersion on spatial resolution of a distributed stress sensor using birefringence optical fiber
Distributed stress sensor with a scanning Michelson white light interferometer can be used to detect stress distribution and its value by analyzing polarization mode coupling caused by stress field in PMFs (polarization maintaining fibers). In the measurement of polarization coupling, the birefringence in sensing fiber is usually considered to be wavelength-independent. The spatial resolution o...
متن کاملMethod for improving the resolution and accuracy against birefringence dispersion in distributed polarization cross-talk measurements.
We present a novel method for improving the spatial resolution and amplitude accuracy of distributed polarization cross-talk measurements in a polarization maintaining (PM) fiber against its birefringence dispersion. We show that the broadening of measured polarization cross-talk peaks caused by birefringence dispersion can be restored by simply multiplying the measurement data with a compensat...
متن کاملSimple Method for Polarization Dispersion Measurements in Long Single-Mode Fibres
The study of polarization dispersion in standard single-mode fibres takes on a growing importance, because the delay between polarization modes causes pulse broadening and may become predominant in multigigabit long-span optical links. The combined effects of weak birefringence and fluctuating mode coupling result in a stochastic behaviour of the polarization dispersion and of the output polari...
متن کاملPrecision measurement of modal birefringence of highly birefringent fibers by periodic lateral force.
Applications of single-mode fibers to coherent optical fiber communication systems1 and fiber sensor systems2 require a definite state of polarization along the fiber length. Polarization-maintaining fibers such as elliptically clad3 and stress-applied4 single-mode fibers have a high internal birefringence that exceeds perturbing birefringence and produces linear polarization along the fiber. O...
