Probe Beam Amplification Via Two and Four Wave Mixing in a Kerr-Like (Liquid Crystal) Medium
Iam-Choon Khoo,T. H. Liu +1 more
TL;DR: Probe beam amplification in a Kerr-like medium, e.g. a nematic liquid crystal film via 2-wave mixing is possible if it is stoke shifted relative to the pump beam.
Proceedings ArticleDOI
Nanosecond And Picosecond Laser Limiting With Highly Nonlinear Organic Liquid Cored Fiber Array
Proceedings ArticleDOI
Supra-photorefractivity in C60 and carbon-nanotubes-doped nematic liquid crystals
TL;DR: Khoo et al. as discussed by the authors reported theoretical and experimental studies of supra-photorefractive nematic liquid crystals doped with C60 and/or Carbon nanotubes.
Proceedings ArticleDOI
Liquid crystal-modulated spontaneous emission via plasmonic waveguide cladded with low index metamaterials
TL;DR: Using the liquid crystal-metal-low index metamaterial waveguide which supports surface plasmon polaritons, an active modulation of spontaneous emission was demonstrated in this article, which can be modulated from 131γ 0 to 327γ 0 by varying optical axis.
Proceedings ArticleDOI
Phototunable sub-wavelength grating and 3D photonic crystal infiltrated with photosensitive nonlinear liquid crystal
Atsushi Shishido,Ivan Divliansky,Suzushi Nishimura,G.L. Egan,M. V. Wood,Min-Yi Shih,Iam-Choon Khoo,K.E. Mallouk,Theresa S. Mayer +8 more
TL;DR: In this paper, surface relief gratings inscribed on the glass windows of NLCs are used for aligning NLC cells, and the authors demonstrate that similar aligning action may also be engendered by surface relief [1D and 2D] gratings.
