This cavity comprises a set of aligned pillars, where the pillars are embedded in a cladding. At least one of the pillars has a sandwich structure, wherein a layer of nonlinear optical material is between two layers of materials having, each, a refractive index that is higher than the refractive index of the nonlinear optical material. The invention can furthermore be embodied as an all-optical modulator or an all-optical transistor, comprising a photonic crystal such as described above. Finally, the invention is further directed to methods for modulating an optical signal, using such a photonic crystal cavity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"One-dimensional photonic crystal with pillars having a layer structure","description":"The present invention is notably directed to a (quasi) one-dimensional photonic crystal cavity.
