Abstract

Presented article shows the effect of using ZnS:Mn nanoparticles in the solution of higher alkanes on the light wave propagation in a biconical, adiabatic optical fiber taper. The used mixture of alkanes with nanoparticles forms a special cladding surrounding a fiber taper. Described studies show change of beam intensity depending on mixture temperature and its state of aggregation. Tests were carried out in a wide spectral range from the visible up to infrared wavelengths. The taper was made of a standard single-mode telecom fiber, pulled out to a length of 20.0 ± 0.5 mm and the diameter of the taper waist is 14.0 ± 0.2 μm. Such taper causes the beam to leak out of a waist structure and allows to add an external beam-controlling cladding material. The built-in sensor containing nanoparticles operates on the on-off principle. Nanoparticles added to the alkanes cause increase of hysteresis in a heating and cooling process. Such mixture makes also a significant shift of temperature characteristic in a heating process in which mixture change their physical state with a simultaneous slight shifting of the characteristics during cooling. Depending on the source used, weakening or amplification of the signal was obtained after switching to the liquid state.
