High-power laser optical fibers rely on carefully engineered core and cladding structures to guide both pump light and the laser signal. This article explains how these fibers are built, what materials are commonly used today, and why ultra-low-refractive-index claddings are of growing interest when approaching system performance limits.
Refractive index is a subtle material property that quietly shapes how light behaves in optical systems. This introductory article explains what refractive index is, why it matters in optical design, and why unusually low-index materials enable new optical applications.
Chromis Technologies and the University of Kansas have earned a U.S. patent for a new fluoropolymer-coated membrane that separates azeotropic refrigerant blends. This game-changing innovation enables high-purity HFC-32 recovery, offering a scalable solution to one of the HVAC industry's toughest environmental challenges.
Chromis Technologies has secured a Japanese patent for its advanced amorphous crosslinked fluorinated copolymers — materials designed to enhance gas separation membranes used in natural gas processing, hydrogen purification, and refrigerant recovery. These high-performance polymers offer exceptional durability, chemical resistance, and selectivity, enabling more efficient and reliable membrane-based gas separation systems.
Kick off your deep dive into advanced surface engineering with amorphous fluoropolymers (AFPs) — materials known for their low surface energy, chemical resistance, and optical clarity. Part 1 explains how AFPs provide consistent, high-performance coatings without the need for surface treatments. It also outlines key properties that make them effective in applications requiring controlled wettability, durability, and processing flexibility. Later posts will explore how AFPs enable precise tuning of surface behavior at the micro and nano scale.
Optical interposers may be the future of chip-to-chip communication, but their success hinges on one overlooked detail — the materials used to build the microscopic waveguides that guide light. Silicon and glass dominate today, yet amorphous fluoropolymers like CYTOP®, Teflon AF™, and next-generation CyclAFlor® could solve persistent challenges in coupling and loss management — making them unlikely but promising contenders in reshaping the future of semiconductor packaging
Modern computer systems are running into a traffic jam. Chips like CPUs, GPUs, and accelerators can crunch data faster than ever — but the copper “roads” that connect them are maxing out. The result? Slower performance, rising power use, and more heat. Optical interposers offer a new express lane — tiny light-guiding channels that promise faster, cooler, and more efficient communication between chips. And the materials used to build those channels — silicon, glass, and even advanced polymers like CyclAFlor® — may be just as important as the technology itself.
This article explores how amorphous fluoropolymers (AFPs) are enabling advanced technology innovations through their unique combination of optical clarity, low surface energy, and chemical resilience.
