TAMPERE, Finland, May 11, 2022 — Researchers at Tampere University collaborated with colleagues at the University of Warsaw and the University of Burgundy France-Comté to create a supercontinuum light source in the mid-infrared, using a nonsilica, graded-index, multimode fiber. The collaborators generated a two-octave supercontinuum in the fiber, which could create a path toward bright, ultrabroadband light sources for applications in the mid-infrared that require high spatial beam quality and high power. The researchers said the optical fiber could be used in environmental sensing, molecular fingerprinting,...Read full articleRelated content from Photonics MediaARTICLESInternational Collaboration Employs 2D Materials to Engineer Optical FibersA Jena, Germany-based research team, working with its Australian colleagues, has grown 2D materials directly on optical fibers.

Dispersive effects — physical mechanisms that broaden transmitted pulses — degrade this process.There are three fundamentally different dispersive phenomena in optical fiber, of which polarization mode dispersion (PMD) is the most complex. In digital multimode fiber systems, a light pulse...Photonics HandbookFiber Optics: Understanding the Basics: Nothing has changed the world of communications as much as the development and implementation of optical fiber.
