“…The temporal method involves measurement of the group delay introduced by an optical fiber which is placed in one of the interferometer arms and evaluating the temporal shift of the peak of the cross-correlation interferogram. As the central wavelength is varied, the relative group delay of different frequency components is observed directly [3]. Alternatively, the spectral distribution of the phase delay over the full bandwidth of the white-light source is obtained in a single measurement by a Fourier transform of the cross-correlation interferogram [4].…”

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.

“…Since the chromatic dispersion depends on the wavelength, the amount of pulse width broadening should be calibrated by considering the operating wavelength of the TOF-LRF system. The amount of the pulse width broadening (Δτ) caused by the chromatic dispersion after the round trip of the pulse laser can be written as [19],…”

We investigate the propagation characteristics of a pulse laser in a time-of-flight laser range finder (TOF-LRF) system with variations in atmospheric conditions, such as temperature, pressure, relative humidity, and the concentration of CO2. The measurement error of distance related with the group velocity change in the TOF-LRF system is analyzed by considering the refractive index of the standard atmosphere with variations in atmospheric conditions. The dependence of the pulse width broadening induced by chromatic dispersion of the standard atmosphere on the operating wavelength and the initial pulse width of the light sources is discussed. The transmission of air with variations in the relative humidity or the concentration of CO2 is analyzed by using different values of absorption coefficients depending on the operation wavelength of the light source in the TOF-LRF system.

“…The propagation loss of the samples from both draws was measured to be 2.0±0.2 dB/m, using the cutback method. A low-coherence interferometric technique [7] was employed to characterise the dispersion profile of the fibre from 1300nm to 1700nm, using a broadband polarized supercontinuum source. The measured dispersion curves for selected fibre samples from the two different draws are illustrated in Fig.1(b).…”
