Soliton propagation and polarization mode-locking in birefringent optical fibres
In recent years much work has been devoted to the development of erbium-doped fibre lasers [ 1-91. because a broad zain bandwidth centred nearly I.54 urn. cegative group velocitv dispersion and tight confinement of optical field allow the exploitation of nonlinear optical effects for very efficient generatlon of ultra-short optical pulses. In the last few years several schemes of fibre soliton ...
متن کاملPolarization-mode interferometry in birefringent single-mode fibers.
An interferometric technique was used to investigate the relative phase delay between polarization modes in birefringent single-mode fibers. Polarization-mode dispersion is directly deduced from the measurements of relative phase delay at different wavelengths. Relative group delays of 20 fsec can be measured in meter-length samples without the need for light-polarizing devices.
متن کاملPolarization 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 کاملDynamic operation of optical fibres beyond the single-mode regime facilitates the orientation of biological cells
The classical purpose of optical fibres is delivery of either optical power, as for welding, or temporal information, as for telecommunication. Maximum performance in both cases is provided by the use of single-mode optical fibres. However, transmitting spatial information, which necessitates higher-order modes, is difficult because their dispersion relation leads to dephasing and a deteriorati...
متن کاملHighly birefringent optical microfibers.
Highly birefringent (Hi-Bi) air-clad silica microfibers (MFs) with wavelength and sub-wavelength scale transverse dimensions are studied theoretically and experimentally. Hi-Bi MFs are taper-drawn from the standard SMF-28 single mode fibers that are "pre-processed" by "cutting away" parts of the silica cladding on opposite sides of the fiber with a femtosecond infrared laser. Such Hi-Bi MFs hav...
