Novel optoelectronic properties in barbed wire nanophotonic structures of indium telluride

Abstract Nanophotonic structures of indium telluride having barbed wire morphology exhibits second order non-linearity. This distinctive non-linear behavior is leading to the generation of second harmonics. Here, we demonstrate low power driven SHG by barbed wire indium telluride system by tuning polarization of the fundamental laser beam in a perpendicular orientation to the axis of the nanostructures. The energy corresponding to the second harmonic is found to be saturating toward higher range of polarizing angles. This study will lead to implementation of the structure in photonic applications negating the influence of polarization to a wide extent. Apart from this, when the nanostructure is subjected to low potential driven Kerr opto-electric non-linearity, the system reveals a critical electric field exhibiting intensity reversal.
