With the success of silicon (Si) solar cell technology, research and development on higher efficiency multijunction cells is gaining much attention. Tandem with a perovskite top Si bottom show particular potential. However, optical modeling such devices complicated by broad range length scales involved; optically thin layers nanoscale features require some version wave optics or even full field...

The relentless quest for processing speed in the range of teraflops and beyond has accelerated the need for scalable, parallel, high-performance computing (HPC) systems. To meet this high bandwidth and low power requirements, optical interconnect-based system architectures are being implemented by the HPC industry. While computer-aided design tools have significantly assisted electronic system ...

Innovations in optical fiber technology are revolutionizing world communications. The focus of this paper is the development of optical fibers that within 20 years displaced copper wire as the transmission medium of choice for most commercial applications in telecommunications systems and computer networks worldwide. High speed and ultra-high capacity of optical communications have emerged as t...

Approximate methods such a Rayleigh scattering and geometric optics have been widely used for the calculation of forces in optical tweezers. We investigate their applicability and usefulness, comparing results using these approximate methods with exact calculations.

Optical MEMS subsystems are complex compositions of varied components that can include optical fibers, freespace and guided wave optics, drive electronics, control systems, MEMS chips, and packaging. Good engineering practice requires that each of these components be designed with the system application in mind. In general, there are two approaches to the design of complex integrated systems. T...

An analytical model is presented that is able to describe the performance of OCT systems in both the single and multiple scattering regimes simultaneously. This model inherently includes the shower curtain effect, well-known for light propagation through the atmosphere. This effect has been omitted in previous theoretical models of OCT systems. It is demonstrated that the shower curtain effect ...

Optical flow estimation is one of the oldest and still most active research domains in computer vision. In 35 years, many methodological concepts have been introduced and have progressively improved performances , while opening the way to new challenges. In the last decade, the growing interest in evaluation benchmarks has stimulated a great amount of work. In this paper, we propose a survey of...

The Multimedia Modeling Language (MML) is a platformindependent modeling language for model-driven development of interactive multimedia applications. Using models provides several advantages like well-structured applications and better coordination of the different developer groups involved in the development process. However, the creative tasks – like graphical design of the user interface an...
