As PIC Production Ramps Up, Fabricators Eye Alignment Options
Modern silicon photonic integrated circuit (PIC)-based devices offer many advantages compared to standard electronic integrated circuits. PIC devices can be manufactured using many of the same wafer-and-chip fabrication processes, but they consume less power, produce less heat, and can transmit data at higher speeds, without sacrificing signal strength or quality. And it is now clear that these advantages will have a transformative impact on a range of emerging technologies.

Industrial Femtosecond Laser Advancements Power Next-Generation Applications
Today, femtosecond lasers find use in a wide range of applications, including eye surgery, fabrication of implantable medical devices, photovoltaics scribing, surface functionalization, glass cutting, and polymer film cutting for the manufacture of displays and microelectronics. In micromachining applications, there is an especially strong demand for higher power and repetition rates to achieve the higher throughputs necessary for high-volume manufacturing.

Lighting Advancements Add Muscle to Machine Vision
LED efficiency gains have allowed machine vision lighting suppliers to develop LED-based options with sufficient brightness to replace tungsten incandescent bulbs and halogen-based illumination systems. While some industrial settings use cool white lights for illumination, many machine vision applications rely on colored, infrared, and ultraviolet LEDs to optimize key details in captured images.

Achromatic X-Ray Lens Opens Pathways in Microscopy, Access to Light Sources

Scientists at Paul Scherrer Institute developed an achromatic lens for x-rays that allows x-ray beams to be accurately focused on a single point even if they have different wavelengths. The lens will make it easier to study nanostructures with x-ray light, supporting R&D in materials science, microchips, and batteries.

Laser Measurement Solutions for Materials Microprocessing Applications
Wed, Jun 15, 2022 11:00 AM - 12:00 PM EDT
Mark Slutzki, product manager at Ophir, shares innovative solutions for the challenges that accompany materials microprocessing applications. Those who use lasers in applications, such as drilling via holes in PCBs, organic LED display lift-off, and cutting smartphone cover glass, are faced with these challenges. While the combination of laser parameters enables new and innovative processes, they can also cause unexpected damage to the measurement tools used to keep the process stable. These parameters include ultra-short pulse duration, high repetition rates, short wavelengths, and many others. Sponsored by Ophir, LaserPoint srl, and DataRay Inc.
