How to Test Devices Used in Optical Communications Systems

As signal rates approach 50 Gb/s, bandwidth demand has outpaced conventional circuit boards. Engineers are now turning to PAM4 signaling rather than conventional NRZ as the most viable solution to these design challenges.

New Microscope Uses Adaptable Mirror to Create Clearer Images

The National Institute of Biomedical Imaging and Bioengineering (NBIB) has developed a microscope that increases resolution and contrast in thick biological samples. The new microscope improves on its predecessor by combining two-photon laser scanning microscopy (2PM) with instant structured illumination microscopy (ISIM). Key to the development, was including adaptive optics (AO) to rapidly correct distortions.

Flexible Liquid Lens Simplifies Inspection

When you buy a new car, you can choose from a wide range of exterior and interior features, transmission and dynamics, and safety bundles, to configure your individual vehicle. From the point of view of engine manufacturing, this entails a wide range of designs and sizes. To meet demands for high quality, the manufacturer must test their engines according to industry-specific guidelines and quality standards. Industrial vision systems make an important contribution to quality assurance and increased efficiency in engine manufacturing. There used to only be a small range of products, whereas nowadays fully automated evaluation of a wide variety of large components and complex geometries is required. A single component may call for as many as 100 features to be inspected in different positions.

Dr. Keiko Munechika, Manager, Nanofabrication, aBeam Technologies, Hayward, CA

Dr. Munechika — along with Alexander Kosh­elev and Giuseppe Calafiore at aBeam Technologies, and Stefano Cabrini at the Molecular Foundry at Lawrence Berkeley National Laboratory — is developing a process that would enable widespread adoption of nano-optic technology. The team perfected a technique for fabricating a Campanile probe, whose tapered, four-sided shape resembles the top of the Campanile clock tower on UC Berkeley’s campus. The probe focuses an intense beam of light onto a much smaller spot than is possible with current optics.

Introducing a Novel Spectral Analysis System for Measuring High-Performance Thin-Film Optical Filters

Alluxa offers and manufactures high-performance optical thin films that are used in wide ranging applications including life sciences, research, semiconductor and LIDAR. All of Alluxa's thin-film optical filters and mirrors are hard-coated using a proprietary plasma deposition process on equipment that was designed and built by our team. This allows us to repeatably produce the same high-performance optical thin films in all of our coating chambers.

Writing with Light: An ‘Etch A Sketch’ Electrical Circuit

Physicists from Washington State University (WSU) have used lasers to draw conductive circuits into a crystal. The achievement demonstrates a new kind of transparent, three-dimensional electronics: circuits that can be erased and reconfigured, like the drawings of an Etch A Sketch.

Asphere Measurement System

The AspheroCheck UP from TRIOPTICS (Weden, Germany) is designed with a completely automated measurement process that requires no manual interaction to accurately measure aspheres. Lenses with aspherical surfaces are frequently used in small, light, high-performance optics to reduce spherical aberration. While the decentration of an aspherical surface can be determined with the centration measurement that is also used for spherical lenses, determining a possible tilt requires an additional, off-axial test.
