“…Fortunately, the measurement of the chromatic dispersion of a fiber sample is still possible in the vicinity of the stationary-phase point if one shifts it in successive steps to different wavelengths [8]. The feasibility of the interferometric techniques has been demonstrated in measuring the dispersion in microstructured and holey fibers [9,10,11]. To the best of our knowledge, non of these methods directly measure the dispersion of group effective index.…”

Abstract:We present a new method for measuring the group dispersion of the fundamental mode of a holey fiber over a wide wavelength range by white-light interferometry employing a low-resolution spectrometer. The method utilizes an unbalanced Mach-Zehnder interferometer with a fiber under test placed in one arm and the other arm with adjustable path length. A series of spectral signals are recorded to measure the equalization wavelength as a function of the path length, or equivalently the group dispersion. We reveal that some of the spectral signals are due to the fundamental mode supported by the fiber and some are due to light guided by the outer cladding of the fiber. Knowing the group dispersion of the cladding made of pure silica, we measure the wavelength dependence of the group effective index of the fundamental mode of the holey fiber. Furthermore, using a full-vector finite element method, we model the group dispersion and demonstrate good agreement between experiment and theory.

This work is aimed at implementation and practical verification of effective index approach applicability to microstructured fibers modeling. In particular, the Effective Index Method, both in scalar and fully vectorial form, is presented and discussed with respect of its potential applications for fast and accurate modeling of chromatic dispersion of index guiding microstructured fibers.The developed models, implemented in Matlab environment, allow visualization of the dispersion profiles of index guiding microstructured fibers with hexagonal lattice. To verify accuracy and define the applicability range of developed models, the results of modeling were confronted with the sparse experimental data, reported up to now in scientific papers. The satisfying agreement between numerical and measured results has been obtained, confirming the accuracy of developed model and its applicability to fast analysis and designing of microstructured fibers with dielectric core.

“…16 The feasibility of the interferometric techniques has been demonstrated in measuring the dispersion in silica or polymer microstructured and holey fibers. [17][18][19][20][21][22][23][24] The huge interest in microstructured and holey fibers has largely been due to the possibility of manipulating the dispersion profile by modifying the microstructure. This has allowed researchers to shift the zero-dispersion wavelength of silica fibers to below 800 nm by reducing the core size.…”

We present the results of interferometric measurements of chromatic dispersion of polarization modes in holey fibers over a broad spectral range (e.g. 500-1600 nm). First, a spectral interferometric technique employing an unbalanced Mach-Zehnder interferometer with a birefringent holey fiber in the test arm is used for measuring the wavelength dependence of the differential group effective index of the one of the polarization modes supported by the fiber. We apply a five-term power series fit to the measured data and by its differentiation we obtain the chromatic dispersion. Second, a spectral interferometric technique employing a tandem configuration of a Michelson interferometer and the holey fiber under test is used for measuring the group modal birefringence in the fiber. From the measurements, the differential group effective index and the chromatic dispersion of the other polarization mode supported by the fiber are retrieved. We confirmed that the measurement results agree well with that specified by the manufacturer. We also measured by these techniques the chromatic dispersion in other birefringent holey fiber.
