Rare-Earth Doped Fibers Deliver Critical Elements to Dynamic Systems

Industry’s favor for rare-earth doped fibers increased greatly in the last four decades. Erbium-doped telecom fiber amplifiers, for example, and ytterbium- or thulium-doped high-power lasers are widely used for many industrial and science applications. Following the development and introduction of these specialty fibers in the 1980s, the adoption of rare-earth doped fibers and the photonic systems that they support did not occur immediately. Yet even as the use of these fibers advanced toward, and ultimately achieved, ubiquity, the fundamental mechanisms behind their performance are largely unchanged. Read Article

Bottlenecks in Process and Production Hinder Micro-LED Adoption

Manufacturing challenges, such as precision placement and process repeatability, which are necessary to ensure optimal performance in final systems, are a core driver of the high cost of micro-LEDs that are currently under development. Fabrication challenges have a direct tie to low production capacity. This is part of a troubling equation that the micro-LED industry is striving to rework. Read Article

Fine and Fast Metal Printing Meets Industrial Challenges in 3D

Two laser-based methods have taken precedence in additive manufacturing during the past several decades. In the first, the laser builds a larger 3D structure out of 2D contours in a powder bed. In the second, a material is deposited on a surface and melted by the laser to create a new surface. As is necessary of other laser processes, it is critical to strike a balance between precision and process speed. Read Article

Liquid Crystal Polarization Gratings

Meadowlark Optics Inc.
These transmissive gratings efficiently (>99.5%) diffract circularly polarized light to the first positive or negative order, based on the handedness of the incident light. By incorporating fast electro-optic half-wave polarization retarders to control the handedness of polarization, we can develop custom LCPG devices and systems with a range of leading capabilities for Coherent Doppler Lidar, High-Definition Time-of-Flight Imaging, Non-mechanical Refocusing in Microscopy, and more.

Mass-Production Method Aims to Drive Metalenses Toward Widespread Commercial Use
To support the mass production of metalenses for use in applications like lidar and miniature medical devices, researchers at Pohang University of Science and Technology and Korea University collaborated to develop two methods for the scalable, wafer-scale manufacture of metalenses operating in the NIR region. The techniques devised by the team could reduce the cost of metalens production by as much as 1000×. Read Article

Researchers Develop Programmable Metafluid
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a programmable metafluid with tunable springiness, optical properties, viscosity, and the ability to transition between a Newtonian and non-Newtonian fluid. The metafluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers that can dissipate energy depending on the intensity of the impact, to optical devices that can transition from clear to opaque.

Let's Talk About Metalenses

Wed, May 29, 2024 10:00 AM - 11:00 AM EDT
From the moment of their initial introduction, metalenses have ignited the creative minds of engineers working in the realms of optics and photonics. LightTrans International’s team, the creators of the optics software VirtualLab Fusion, are dedicated to offering modeling and design tools that assist their clients in exploring the capabilities of metalenses in their respective applications. During this webinar, Frank Wyrowski shares strategies for the design and simulation of metalenses in common application contexts. He is eager to showcase cutting-edge advancements and discuss future plans for expanding these concepts in 2024. He aims to motivate the optics community to share their anticipations regarding the functionalities that an optics software should encompass for the utilization of metalenses. Presented by LightTrans International.
