VCSEL
The US patent office awarded two critical patents to VI Systems. The patents cover applications in datacom, sensing and high-power high-brightness VCSEL array applications: 1. OPTOELECTRONIC DEVICE WITH RESONANT SUPPRESSION OF HIGH ORDER OPTICAL MODES AND METHOD OF MAKING SAME. 2. OPTOELECTRONIC DEVICE WITH ENHANCED LATERAL LEAKAGE OF HIGH ORDER TRANSVERSE OPTICAL MODES INTO ALLOY–INTERMIXED REGIONS AND METHOD OF MAKING SAME. The inventions facilitate the realization of single mode devices at large oxide-confined and/or impurity-intermixing defined aperture diameters and enable on-chip coherently-coupled VCSEL arrays without using of external mirrors. 2D beam steering is enabled when VCSELs or blocks of VCSELs are individually addressable. The grant of the patents provides further recognition of the quality of the innovation being carried out by VI Systems’ team.

VI Systems is proud to announce the EUREKA has labeled its innovative solutions. EUREKA is a European organization established in 1985. It brings together 40 members, including the European Union. The prestigious EUREKA label is given to companies developing high value added projects passing stringent assessment procedures. The label gives VI Systems the recognition of …
