Temperature effect on the light propagation in a tapered optical fiber with a twisted nematic liquid crystal cladding

Joanna Korec, Karol Antoni Stasiewicz, Leszek Roman Jaroszewicz


This paper presents the influence of temperature on optical power spectrum propagated in a tapered optical fiber with twisted nematic liquid crystal cladding (TOF-TNLCC) modulated by an electric field. The measurements were performed for a liquid crystal cell with the twisted orientation of ITO layers, filled with E7 mixture. The induced reorientation of liquid crystal (LC) n-director was measured for visible and near-infrared wavelength range [550-1100 nm] at the electric field range of 0–160 V and temperature range of 20-60 °C. The relation between temperature and the optical power spectrum of the investigated device has been established.
