The linear mode avalanche photodiode detects one or more photons in the light by using a superlattice structure that is matched to suppress impact ionization for a first carrier in the linear mode avalanche photodiode while at least one of 1) increasing impact ionization, 2) substantially maintaining impact ionization, and 3) suppressing impact ionization to a lesser degree for a second carrier. The first carrier having its impact ionization suppressed is either i) an electron or ii) a hole; and then, the second carrier is the electron or the hole."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Linear mode avalanche photodiodes without excess noise","description":"A linear mode avalanche photodiode senses light and outputs electrical current by being configured to, generate a gain equal to or greater than 1000 times amplification while generating an excess nois","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11271130","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.
