The grating coupler includes segments that are positioned with a spaced relationship on a slab layer.

The first and second states may be produced by applying different sets of bias voltages to the segments as the applied stimulus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tunable grating couplers containing a material with a variable refractive index","description":"Structures including a grating coupler and methods of forming a structure that includes a grating coupler.
