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.
