Low Loss, Single-mode, Hollow-core Optical Fibers

Hollow-core fibers are a revolutionary break-through in optical transmission – they allow for light guiding in air over long distances, with potential for ultra-low loss, as well as low nonlinearity. However, hollow core fibers suffer from a trade-off: lowering the loss of the fibers also means that they support higher-order mode propagation, which can impair their use in potential applications such as data communications and high-power pulse delivery and compression. In this talk, we present a new type of hollow-core fiber showing, for the first time, hollow-core fibers that can beat this trade-off, and using the Perturbed Resonance for Improved Single-Modedness, or PRISM, effect we demonstrate low-loss, effectively single mode, hollow core fibers.

Cloud Engineering Tools Make Design Decisions Less Cloudy

The main purpose of engineering software is to help engineers make smarter decisions faster and to avoid sacrificing quality for speed. Cloud technology dramatically improves access to information and people, enabling faster decision-making by you and your engineering team, thanks to the ease of which information is accessed. This webinar, given by the founders of two successful providers will focus on the application of cloud technology in engineering software and its impact on decision-making in two key areas: component selection & change management.

Controlling Surface Chemistry and Morphology to Promote or Prevent Adhesion

We encounter interfacial interactions every day. Our tires grip the road because frictional forces between the rubber and concrete prevent tires from slipping. Conditioner moisturizes hair because it is designed to make contact with each strand to deliver moisturizing agents that separate the strands. Not unlike these interactions, the ability to controllably alter interfacial or adhesion interactions is important for a wide variety of industries from aerospace to marine to space exploration. To control interfacial interactions, both surface chemistry and topography play vital roles.

A Design Engineer's Guide to Specifying Custom Bearings: Optimizing Features and Cost

As an engineer, one of the first lessons of design is to specify standard products if possible. With today’s demands for smaller, more reliable and more cost efficient products, engineers are often faced with significant design and performance challenges. So why should an engineer consider specifying a custom bearing?

Why Does Your Product Break?

Fatigue is often cited as one of the most common forms of operational failure in structures. Its nature is an often apparently premature failure at relatively low, but cycling, stress levels.

High-Performance, Thermally Insensitive Optics

Silicon Carbide has a unique set of thermal and mechanical properties that make it an ideal material for some reflective optics systems. The difficulty of manufacturing lightweight structures with SiC, however, has limited its use to substrates attached to benches made of more forgiving materials.
