The PIC can further include a plurality of optical filters each coupled to the waveguide and outputting resonant optical output to a plurality of optical combiners. Each optical combiner couples the resonant optical output from a corresponding pair of optical filters to output a heterodyned optical signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Photonic integrated circuit using a quantum dot comb laser for heterodyne optical signals","description":"A photonic integrated circuit (PIC) can include a quantum dot comb laser comprising a plurality of channels and a waveguide receiving laser output from the plurality of channels of the quantum dot com","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10488588","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.
