The semiconductor layer has a multi-layer structure including at least an active layer. The current constriction part causes a current to concentrate and flow to a particular area of the active layer. The first electrode or the second electrode is joined to a sub-mount. In one embodiment, the location of the current constriction part in a chip width direction is between the center of one of the first and second electrodes, which is joined to the sub-mount, and the center of the other electrode, which is not joined to the sub-mount, when viewed in the chip width direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor laser element and method of making semiconductor laser device","description":"A semiconductor laser element includes an inclined substrate, a semiconductor layer formed on one surface of the substrate, a first electrode (n-type electrode) formed on an opposite surface of the su","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9692204","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.
