Abstract

We have characterized 3.4 mum wavelength InAsSbP/InAs light emitting diodes grown as double heterostructures by liquid phase epitaxy with a 300 mum wide aperture coupled with As₂S₃ naked fibre. The output power, far field pattern and spectral characteristics depend on chemical composition of liquid being in contact with fibre making feasible evanescent wave analysis of liquids contenting water and/or hydrocarbons, e.g. alcohol
