Such a whispering gallery mode (“WGM”) dip sensor, including (1) a stem, (2) a WGM resonator, and (3) feed and pickup optical fibers, may be made by (a) fabricating the WGM resonator and the stem from an optical fiber; (b) fabricating tapers on the feed and pickup fibers; (c) positioning tapers of the feed and pickup fibers relative to the WGM resonator such that an optical coupling between the tapers and the WGM resonator is established; and (d) mechanically coupling the stem with the feed and pickup fibers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pre-assembled whispering gallery mode resonance sensors, for use as dip sensors or vapor sensors, for example, and methods for making such sensors","description":"A robust sensor, suitable for dipping into fluid wells, includes (a) a stem; (b) a whispering gallery mode (“WGM”) resonator mechanically supported by the stem; and (c) feed and pickup optical fibers ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9804331","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.
