Overview

GLOphotonics is a French photonics company that designs and produces gas-phase photonic components based on an innovative hollow-core micro-structured optical fiber technology. The company was founded to exploit a disruptive platform and key-enabling technology that spun out from Fetah Benabid's research group, first at the University of Bath in the UK and then at CNRS in France. The core of GLO technology is a special optical fiber called hollow-core photonic crystal fiber (HCPCF) and its functionalized form, the Photonic MicroCell (PMC). GLO fibers stand out for their exceptional laser power and energy handling, as well as their versatility. The PMC is described as the first and only photonic component whose functionalities are based on gases. Based on this technology, GLOphotonics develops and commercializes photonic components, modules, and sub-systems. Its product range includes hollow-core optical fibers, laser beam delivery modules, specialty lasers, pulse compressors, sensing modules, and low-latency fiber cables. The company has positioned itself as a world-leading and transformative force in several industry segments, including laser machining, medical and bio-photonics, space, sensing, and datacom. GLOphotonics' mission is to enable its partners to transform their markets by offering unique added-value solutions. For example, in collaboration with laser manufacturers and machine tool integrators, GLO offers bespoke beam delivery modules for ultra-short and ultra-high-power lasers. The GLO Beam Delivery product family aims to be a key differentiator in introducing laser micromachining in verticals such as automotive and consumer electronics. The company also offers specific lasers that existing technologies cannot deliver, such as the UV-CombLas. GLOphotonics serves multiple sectors with products including hollow-core photonic crystal fiber, beam delivery modules, pulse compression systems, frequency conversion and lasers, quantum technology solutions, and telecom technology solutions. Its hollow-core fibers offer advantages such as low latency, high-bandwidth transmission, reduced nonlinear effects, broadband capability, and immunity to crosstalk, making them suitable for high-frequency trading, datacom, and other time-sensitive applications. The company is headquartered in France and operates internationally, partnering with laser manufacturers, machine tool integrators, and telecom operators.

History

GLOphotonics was founded to exploit a disruptive platform and key-enabling technology that spun out from Fetah Benabid's research group, carried out at the University of Bath, UK, and then at the CNRS, France. The core of GLO technology is a special optical fiber, coined hollow-core photonic crystal fiber (HCPCF), and its functionalized form, the Photonic MicroCell (PMC). GLO fibers stand out with their exceptional laser power and energy handling, and their versatility. The PMC is the first and only photonic component whose functionalities are based on gases. Based on this technology, GLOphotonics develops and commercialises photonic components, modules and sub-systems. GLOphotonics products range from Hollow-Core optical Fibers and laser beam delivery modules, to specialty lasers, pulse compressors and sensing modules or low-latency fiber cables. Since its introduction in the market, GLOphotonics has positioned itself as a world-leading and transformative force in several industry segments that cover laser machining, medical and bio-photonics, space, sensing and datacom, to mention a few. The company's mission is to enable its partners to transform their markets by offering unique added-value solutions. For example, in collaboration with laser manufacturers and/or machine tool integrators, GLO offers a large number of bespoke beam delivery modules for ultra-short and ultra-high-power lasers. The GLO Beam Delivery Product family is aiming to be the key differentiator in introducing laser micromachining in verticals such as automotive or consumer electronics. Furthermore, GLO offers specific lasers that existing technologies cannot deliver, such as its UV-CombLas. In ultra-fast laser technology, GLO provides pulse compression solutions. The company has also patented technologies for the telecom industry, offering solutions that normal fibers cannot provide by allowing light to pass through air instead of glass, removing limitations and problems plaguing the telecom industry. GLOphotonics continues to operate as a private company headquartered in France, serving international markets.
