VI Systems gets US patent for 40G VCSEL technology
VI Systems GmbH, a developer and producer of optical devices for data transmission, has received a US patent covering the material composition of optoelectronic devices including VI Systems' 40 Gbit/s vertical cavity surface emitting laser (VCSEL).
The patent "˜Optoelectronic Device with a Wide Bandgap and Method of Making Same', protects the company's proprietary concept of ultra high-speed vertical VCSELs. The invention relates to semiconductor light emitting devices for visible and infra-red spectral ranges, and can therefore also be applied to LEDs targeting the bright red, orange, yellow, or green spectral ranges.
VI Systems' offers engineering samples of its 40 Gbit/s VCSEL at 850nm wavelength as bare die chips or as fibre coupled test modules.
