Optically isotropic fast phase modulation in 3D blue phase photonic crystals.

ABSTRACT: Blue Phase (BP) liquid crystals are self-assembled 3D photonic structures that uniquely combine optical isotropy with ultrafast electro-optical switching. Their cubic symmetry enables polarization-independent behavior, while sub-millisecond response times make them highly attractive for dynamic photonic applications. However, their practical use has typically been limited by their tendency to form disordered polycrystalline domains, resulting in scattering and poor optical performance. In this work, we realized large-area monocrystalline BP structures with a photonic stopband positioned entirely outside the visible range. This eliminates structural coloration and enables a fully transparent, broadband operation without parasitic reflection. The cubic symmetry ensures the system remains opt
