The work describes the technology of a liquid crystal cell with a tapered optical fiber as an element providing light. The tapered optical fiber with the total optical loss of 0.22 ± 0.07 dB, the taper waist diameter of 15.5 ± 0.5 μm, and the elongation of 20.4 ± 0.3 mm has been used. The experimental results are presented for a liquid crystal cell filled with a mixture 1550* for parallel orientation of LC molecules to the cross section of the taper waist. Measurement results show the influence of the electrical field with voltage in the range of 0-200 V, without, as well as with different modulation for spectral characteristics. The sinusoidal and square signal shapes are used with a 1-10 Hz frequency range. Full Text: PDF ReferencesZ. Liu, H. Y. Tam, L. Htein, M. L.Vincent Tse, C.

Abstract This work reports the experimental fabrication and characterization of the Er3+-doped silica microspheres (mS) and numerical investigation of the effects of size and surrounding medium on the optical properties of whispering-gallery-mode (WGM) lasers. The heat melting method of two discharge electrodes was used to produce the Er3+-doped silica mSs of diameters up to several tens of micrometers. The 125-mm diameter single-mode optical fiber was tapered with a cone angle formed by chemical etching in hydrofluoric acid (HF) solutions. It was used to produce the mSs and couple the pumped laser into mS surface as well was coupled out the lasing emission. The WGM lasers at telecom regime of ~1520-1570 nm were characterized in both clockwise (CW) and counterclockwise (CCW) propagation directions. By adjusting the coupling gap between the tapered optical fiber and the mS surface, the selectivity of the multi- or single-emitted modes of the mS laser was achieved. We performed finite-difference time-domain (FDTD) simulations to examine the size dependence and analyze the effect of the surrounding medium’s refractive index on the optical characteristics, such as emission wavelength, intensity, as well as the shape of WGM lasing emission. The facile approach and quantitative investigation of this work has attracted much attention from researchers in the micro-photonic field and may be useful in many applications from tunable single-mode lasing sensing to optical micro-devices.

Abstract We present a new procedure for protecting micro-optical fibers (tapered fibers) by using the 3-dimension (3D) printing technology. A standard single-mode optical fiber was tapered down to the diameter of 1 µm and embedded in a polymeric matrix obtained by an additive manufacturing routine. We show that the proposed structure protects the fiber taper against environmental humidity while keeping permeability to gas flow and the possibility of the realization of gas detection experiments. To our knowledge, this is the first time 3D printed casings were applied to protect fiber tapers from humidity deterioration. We envisage this new approach will allow the development of new fiber taper devices to better resist in humid environments.
