Featured Applications of DEVICE

DEVICE addresses a wide variety of applications involving electrical characterization of silicon-based semiconductor devices. DEVICE specializes in devices that include complex optical stimuli, but also excels at modeling traditional optoelectronic and purely electrical devices. DEVICE is useful for many engineering problems of interest, including:

Integrated Optoelectronics: CMOS Image Sensor Pixel

As CMOS pixel sizes decrease to reduce costs of digital camera systems, there is a corresponding reduction in signal to noise and an increase in pixel cross-talk. DEVICE can model the complex geometries of modern CMOS image sensors. When combined with Lumerical’s FDTD Solutions, DEVICE can accurately model the complete optical to electrical conversion in these devices.

Photovoltaics: Thin-Film Silicon Solar Cell

The optical generation of electrons and holes in micro-structured solar cells typically varies both laterally and vertically on very short length scales within the active Silicon layer. This is in contrast to planar devices where the optical generation is considered to vary with the depth in the Silicon layer. While the ability to engineer the spatial locations where the carriers are generated is a powerful advantage of micro-structured devices, these characteristics need careful design consideration to ensure that the generated carriers may be efficiently collected and are not lost to mechanisms such as surface recombination. DEVICE allows designers to accurately model micro-structured solar cells by allowing for truly arbitrary profiles for optical generation of carriers. These profiles can be easily obtained using FDTD Solutions for a wide variety of solar cell devices such as plasmonic and structured surface designs

Silicon Photonics: Waveguide-Based Optical Modulators

Electrically-coupled optical modulators and detectors are key components of integrated silicon phontonics systems. As the demand for high-performance optical interconnects increases, so will the design requirements for silicon optoelectronic modulators. DEVICE can be combined with MODE Solutions to accurately model and analyze these devices in a complete end-to-end optoelectronic design flow, maximizing efficiency and integration.
