We demonstrate that, in suitably designed cells with undoped nematic liquid crystals, extraordinary-wave spatial solitons can be excited at every applied voltage without adjustments in the input polarization. Their walk-off, hence direction of propagation, is externally controlled over angles as large as 7 degrees. The results pave the way not only to polarization-forgiving generation but also to voltage readdressing of these extraordinary-wave nematicons.
我们证明,在具有未掺杂向列型液晶的适当设计的单元中,无需调整输入偏振,在每个施加电压下都能激发异常波空间孤子。它们的离散,进而传播方向,可在高达7度的角度范围内进行外部控制。这些结果不仅为宽容偏振的产生铺平了道路,也为这些异常波向列子的电压重新调整铺平了道路。
