Blue Phase liquid crystals have lately become the focus of extensive research due to their peculiar properties and structure. BPs exhibit a highly organized 3D structure with a lattice period in the hundreds of nm – they are considered 3D photonic crystals – which is achieved by the self-assembly of the liquid crystal molecules into periodic cubic structures, producing bright selective Bragg reflections. This all-optical approach allows for a seamless fast remotely controlled optical switch between two 3D photonic crystals in different cubic crystal systems and between a photonic crystal and an isotropic matrix. All-optical photonic systems such as these hold great promise for the development of tunable and efficient photonic devices, specifically the dynamic optical filters and sensors, as they enable light-driven modulation and sensing applications with unprecedented versatility.
