The optical wavelength separator is configured to substantially direct individual wavelength ranges of light received at an input optical port to separate lateral areas of said layer of liquid crystal. The electronic controller is configured to apply the voltages such that at least one neighboring pair of the lateral areas have refractive indexes modulated along a first direction and are separated by a guard band of the pixel regions along a different second direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical wavelength selective switches with guard bands","description":"An apparatus includes an optical wavelength selective switch that includes an optical wavelength separator, a layer of liquid crystal having a two-dimensional array of s electrically operable pixel re","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10505656","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.
