VI Systems concentrates on the design and qualification of ultrahigh-speed
components for data transmission and high accuracy optical sensors. The
manufacturing of optical components, integrated circuits and opticalpackaging is outsourced to foundries and electronics manufacturing service
companies.
Our optical components and integrated products are sold to major
manufacturing companies, who then use these components to produce highspeed optical modules which are the basis of virtually all optical datatransmitting systems.
VI Systems leads a trend in the fiber optic communications industry weremanufacturers increasingly seeking to outsource production to specialized
foundries in order to reduce overall costs and accelerate time to market.

Thermal analysis
Simulation tools for the thermal modeling of semiconductor packages have now
become routine in most design processes. From early spreadsheet-type tools thatwere in vogue a couple of decades ago, many designers now use sophisticatedFEA (Finite Element Analysis) or CFD (Computational Fluid Dynamics) tools, andinterface their mechanical CAD data directly into their analysis.

Modelling and simulation
VCSELs are key components for optical interconnects and are widely applied inhigh-performance computers and data centers. Single transverse-mode VCSELs
are used in sensing, illumination, and display applications. The image below showsa cross section of the simulated electric field of the fundamental and first excited
optical modes of an oxide-confined aluminum gallium arsenide-based leaky VCSEL.
