    VI Systems Awarded Two Optoelectronic Patents

    Article obtained from Photonics RSS Feed.

    The U.S. Patent Office has awarded two critical patents to VI Systems GmbH for applications in advanced data communications, sensing, and high-power vertical-cavity surface-emitting laser (VCSEL) arrays.

    The first patent is for an optoelectronic device with resonant suppression of high-order optical modes. The second patent is for an optoelectronic device with enhanced lateral leakage of high-order transverse optical modes into alloy-intermixed regions.

    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.
