    Spontaneous Achiral Symmetry Breaking in Liquid Crystalline Phases

    It is well known that spontaneous deracemization or spontaneous chiral resolution occasionally occurs when racemic molecules are crystallized. However, it is not easy to believe such phenomenon will occur when...

    Second-harmonic generation in distributed feedback ferroelectric liquid crystal cells

    The helicoidal structures in ferroelectric liquid crystals can be utilized to realize a special phase matching for the second-harmonic generation (SHG) when two counter-propagating fundamental waves are normal...

    Helicoidal distributed-feedback cavity action in a ferroelectric liquid crystal

    Second-Harmonic (SH) generation was observed in homeotropically aligned ferroelectric liquid-crystal cells using fundamental light propagating along the helicoidal axis. Relatively strong SH light was observed...

    Probing liquid crystals nonlinearly

    Optical second-harmonic generation has been used to study the anisotropic orientation behavior of liquid-erystal siloxane molecules embedded in a nematic and/or ferroelectric host matrix. All of the studied gu...
