Impact Statement: In this paper, we demostrate compact, broadband directional couplers using sub-wavelength gratings for the silicon-on-insulator platform. The dispersion properties of the optical ...

We sell different types of products and services to both investment professionals and individual investors. These products and services are usually sold through license agreements or subscriptions ...

Simon Buddle discusses the pros and cons of single-line KNX topology, and the benefits of using line couplers to support separate lines and power supplies, particularly in apartment blocks. As we move ...

Abstract: In this paper tapered velocity mode-selective couplers are presented. These tapered couplers are approximately adiabatic devices which unlike standard mode-selective couplers, do not rely on ...

Part 1 examines the need for and basic principles of directional couplers and explores some of the construction techniques and implementations. Figure 1 shows the basic arrangement of a single ...
