Electrically tunable momentum space polarization singularities in liquid crystal microcavities
Przemysław Oliwa, Piotr Kapuściński, Maria Popławska +10
Momentum space polarization singularities of light appear as vectorial twists in the scattered and radiated far field patterns of exotic photonic structures. They relate to importa…
