The waveguide core in the first and second passive regions including one of sol-gel and SiO2 surrounded by cladding including one of sol-gel and SiO2. The cladding in the passive regions having a first refractive index, the waveguide core in both regions having a second refractive index at least 0.01 higher than the first refractive index. The waveguide core in the active region including sol-gel, a cladding layer of sol-gel positioned between the insulating layer and the waveguide core, the refractive index of the waveguide core is at least 0.01 higher than the refractive index of the cladding layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active region-less modulator and method","description":"A polymer modulator including a waveguide core defined over an insulating layer and having a first passive region including a light input, a second passive region including a light output, and an acti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11520175","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
