“…In particular, some applications take advantage of the possibility of adapting POF into a U-shape to facilitate access to the evanescent field [7] even with just a lateral polishing of the fiber [8] to increase the interaction with the outer medium. A different possible configuration involves the interrogation of a dye-doped core POF using a side-illumination technique [11,12]. In this case a laser source is laterally focused in the fiber core to excite the inner fluorescence.…”

“…The solid lines in the Fig. 4(a) are the theoretical curves obtained by using a model which represents the light intensity after propagating a distance z from a point source [7]. Since it has been taken the same absorption coefficient for both fibres, the only difference between the theoretical curves is the complementary critical angle which is related to the refractive-indices [1,12].…”

“…We have measured the emitted intensity and its far field pattern (FFP) as a function of propagation distance through the two types of fibres by using the sideillumination technique. This method, based on transverse excitation for measuring the optical attenuation in doped fibres, was first proposed in 1999 by Kruhlak and Kuzyk [6,7]. Since the method is non-destructive, it constitutes an alternative technique to the traditional methods like the cutback method or the bulk measurement.…”

The effect of the cladding on the emission properties of doped plastic optical fibres has been analyzed by using the side‐illumination technique. For that purpose, the photoluminescence spectra of cladded and uncladed plastic optical fibres, both with the same doped core material, have been compared. In particular, we study the dependence of the emitted intensity on the launching angle and on the propagation distance. We also analyze the angular distribution of the emitted light as a function of the propagation distance through the fibres. Using this information, we have characterized the optical losses in both kinds of optical fibres. The study has been performed in plastic optical fibres doped with a conjugated polymer.

Abstract-While nonlinear optical spectroscopy is becoming more commonly used to study the excited states of nonlinearoptical systems, a general theory of inhomogeneous broadening is rarely applied in lieu of either a simple Lorentzian or Gaussian model. In this work, we generalize all the important linear and second-order nonlinear susceptibility expressions obtained with sum-over state quantum calculations to include Gaussian and stretched Gaussian distributions of Lorentzians. We show that using the correct model to analyze experiments that probe a limited wavelength range can be critical and that this theory is better able to fit the subtle spectral features -such as the shoulder region of a resonance -when both models produce qualitatively similar responses.
