Linear and nonlinear characterization of optical liquids in the visible and near-infrared spectral region — •Stefan Kedenburg, Andy Steinmann, Timo Gissibl, Marius Vieweg, and Harald Giessen — 4th Physics Institute and Research Center SCOPE, University of Stuttgart

Liquid-filled fibers and optofluidic devices require infiltration with a variety of liquids whose linear and nonlinear optical properties are still not well known over a broad spectral range, particularly in the near-infrared.

Hence, dispersion and absorption properties have been determined for carbon disulfide, nitrobenzene, toluene, and carbon tetrachloride.

For the refractive index measurement a standard Abbe refractometer in combination with a white light laser and a technique to calculate correction terms to compensate for the dispersion of the glass prism has been used. New refractive index data and derived dispersion formulas between a wavelength of 500 nm and 1600 nm are presented in good agreement with sparsely existing reference data.

The absorption coefficient has been deduced from the difference of the losses of several identically prepared liquid filled glass cells or tubes of different lengths in the wavelength region between 500 nm and 1750 nm.

The nonlinear refractive index has been characterized by self-phase modulation in liquid-filled hollow core fibers.
