Designing Optics for Manufacturability: Bridging the Gap Between Engineering and Production
In the fabrication of optical components, one of the most common — and most critical — challenges to overcome originates well before the start of manufacturing. Despite abundant technical knowledge, many optical engineers responsible for the design of optical components ranging from basic plano windows to precision mirrors and advanced laser optics have never set foot in a manufacturing shop. This disconnect often results in overspecified or impractical designs that increase costs, lead time, and complexity without offering any improvement to performance.

Photonic Microwave Sources Divide Noise and Shift Paradigms
Radio frequency and microwave signals are central to ubiquitous technologies such as radar, communications, and positioning, navigation, and timing. They also form the backbone of today’s frequency standards. Their importance extends further into research, where they play a crucial role in fundamental scientific experiments, including those using very long baseline interferometry in radio astronomy. Optical frenquency division enables the precise scaling of optical frequencies across orders of magnitude, extending down to the microwave and RF domains.

Precision Filters Hold the Key to Measuring How We See
Whether a smartphone screen, automotive dashboard, or surgical monitor, the first thing that one notices upon viewing a scene or object is the color. While this has been true throughout human history, today’s technology is consistently displaying higher saturated colors than ever before. Many displays cover the DCI-P3 gamut, defined 20 years ago. Others are now approaching the ITU-R Recommendation BT.2020 gamut, which spans a wider color range than the DCI-P3 space.

IR Filters for Thermal Imaging
Spectrogon US Inc.
Spectrogon manufactures infrared filters and windows with high transmission, high rejection outside the passband, while maintaining excellent coating uniformity for thermal imaging and gas detection applications such as cryogenically cooled IR detectors and uncooled microbolometers. Our filters and windows range in dimension from Ø6.0 to Ø200.0 mm, with dicing capabilities down to as small as 1.0 × 1.0 mm.

Fusion Ignition Achieved Using Sophisticated Diagnostic Tool
A collaborative research team from Los Alamos National Laboratory and Lawrence Livermore National Laboratory has implemented its Thinned Hohlraum Optimization for Radflow window diagnostic tool in its latest ignition experiment at the National Ignition Facility. The team conducted an experiment that generated a yield of 2.4 +- 0.09 MJ of energy and created a self-sustaining feedback loop called a “burning plasma.”

Illinois Team Pioneers VCSEL Breakthrough
Despite the ubiquity of VCSELs, found in everything from computer mice to face-scanning hardware in smartphones, these devices remain an active field of research, with many in the field exploring new applications. The laboratory of Kent Choquette at the University of Illinois Urbana-Champaign has developed a design in which light from multiple VCSELs combines to form a single coherent pattern called a “supermode.”

Low-Cost Microphone Listens with Light
Traditional microphones capture tiny vibrations on the surfaces of objects caused by sound waves and turn them into audible signals. A microphone developed by researchers at the Beijing Institute of Technology operates differently: Rather than sound, the microphone listens with light. This light-enabled microphone is able to pick up sounds in situations where traditional microphones are ineffective, such as through a glass window.
