Phys.org reports that the pink cricket ball was introduced for day-night matches more than a decade ago and approved for trials by the International Cricket Council this June; research shows its visibility under different lighting conditions is not always ideal.
An OFweek article analyzes how silicon carbide optical waveguides are moving from an alternative AR performance material to a core element of mass production, with materials, chips and modules all scaling up simultaneously. It cites actions including Aifalong's oversubscribed Series B round of more than 100 million yuan to build an 8-inch silicon carbide metasurface optical waveguide chip production line, Guangna Siwei's financing of nearly 200 million yuan, and Goertek Optics' F50Se module achieving a 50-degree field of view. The author believes cost, processing yield and supply chain maturity remain the three hurdles before large-scale deployment, with the current average price of a SiC waveguide chip at 250-350 US dollars.
A Laser Focus World article notes that mirrors or filters on satellites cannot be returned to the factory for repair, so space optical coatings must succeed the first time, requiring rigorous design, documentation and environmental validation.
Optical superlattice crystals command high prices and face high barriers in poling processes, while domestic substrate materials lag behind, leaving substantial room for domestic substitution.
C114 profiles the leading manufacturers and competitive landscape in the thin-film lithium niobate modulator market during the first year of mass production.
More companies are positioning themselves in smart dimming coated glass, while relevant specifications and standards continue to improve.
Fluorinated photosensitive polyimide enables direct photolithographic patterning and offers superior dielectric and optical properties.
Fujia Gallium Chairman Qi Hongji gave an exclusive interview to the Asia Gallium Oxide Alliance during APCSCRM 2025, describing the company's journey from the laboratory to gallium oxide industrialization. He said the VB method 6-inch single-crystal growth technology greatly reduces precious metal consumption and lowers single-crystal substrate production costs, and introduced a one-click crystal growth system combining artificial intelligence and precision control.
Fujia Gallium Chairman Qi Hongji delivered an invited presentation titled "How Far Is Gallium Oxide Industrialization for Ultra-Wide-Bandgap Semiconductors?" at the 5th Youth Academic Conference on Artificial Crystal Materials, dividing gallium oxide industrialization into four stages: availability, usefulness, ease of use, and desirability. He believes that once single crystals and epitaxy break through the 6-inch barrier, gallium oxide devices can accelerate iteration using mature silicon power device tape-out lines, while material defects, P-type materials, heat dissipation, and reliability remain key future research topics.
A front-page lead feature in People's Daily spotlights Hangzhou Fujiagallium Co., Ltd., a company incubated by the Hangzhou Institute of Optics and Mechanics, as a model case of the institute's role in industrializing scientific and technological achievements. The gallium oxide single crystal developed by Fujiagallium grows at a high temperature of 1800 degrees Celsius and targets high-power power electronic devices and ultraviolet detectors. The Hangzhou Institute of Optics and Mechanics' proof-of-concept center opened up equipment such as Hall effect test systems and X-ray diffractometers, saving one to two years in industrialization.
Fujian's laser industry is anchored by upstream crystal materials, laser sources and precision optical components, with more than 200 companies clustered in Fuzhou's optoelectronic information supply chain. Fujian Castech Crystals, Haichuang Optoelectronics, Zhongke Guanghui and Fuzhou Focuslight respectively specialize in optical crystals, LiDAR light sources, fiber lasers and precision optical components. Regional development is also supported by manufacturing demand, cross-strait cooperation with Taiwan, research institutions and local policies.
