Polarization-mode interferometry in birefringent single-mode fibers.
نویسندگان
چکیده
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.

Precision 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...

متن کاملFiber-Based Interferometry and Imaging
Single-mode optical fibers are playing an increasing role in astronomical interferometry, e.g., in high-accuracy visibility measurements and in nulling interferometry. However, such observing modes typically involve only small numbers of fibers. On the other hand, some recently proposed observing techniques call for arrays of single mode fibers coupled to arrays of sub-apertures within a large ...
متن کاملCorrelation theory of polarization mode dispersion in optical fibers
A general theory is used to describe the correlation properties of polarization mode dispersion (PMD) in a birefringent, linear, dispersive medium such as optical fibers. The theory includes the effects of frequency dependence of birefringence on all orders, and it is capable of providing statistical information about secondand higher-order correlations among the polarization and PMD vectors. W...
متن کاملUse of Polarization-Optical Time Domain Reflectometry for Observation of the Faraday Effect in Single-Mode Fibers
Magnetooptic Faraday rotation in a strongly twisted singlemode fiber is measured using polarization-optical time domain reflectometry (POTDR) in which a light pulse of 904 nm wavelength makes a roundtiip along the fiber. The experimental results are in good agreement ,with the calculations, and the Verdet constant thus obtained is 0.86 X 10" min/G. cm at h = 904 nm. T HE Faraday rotation of pol...
