Unrivalled visible and infrared transmission
From swtichable optical circuits to multistate memory. Easily swithcable without needing power to maintain state
Transmitting to 7 micron and beyond for remote sensing and thermal imaging
The grant underpinning the current Chalcogenide Advanced Manufacturing Partnership (ChAMP) is due to finish in early 2021. We are now in final stages of defining a follow-on program of work. Built around the feedback we have received from our many industrial and academic collaborators this will focus on:- Synthesize of raw materials to atomic level…
The ChAMP program has been investigating the use of phase change materials in integrated silicon photonics to build reconfigurable optical routers.
The concept is to use a pixelated pattern of phase change chalcogenide material on top of a multimode interference waveguide (MMI) to guide light towards a selected output.

ChAMP has demonstrated for the first time fabrication of a core-clad GLS-Se glass-based optical fibre using extrusion. For initial demonstration two glass compositions similar in thermal and mechanical characteristics were chosen, with only a 5wt% difference of Ga2Se3 between core and cladding. Billets of 30mm in diameter and different thicknesses were fabricated using established and repeatable melt quenching process in our facilities
…Visit us at Stand 121 Hall B2 at LASER World of Photonics in Munich 24-27 June 2019 to learn more of the latest developments in Chalcogenide glass development including the latest moulded lens samples, progress in optical fibre development and extended infrared transmission.
In response to many requests from optical designers and using the latest visible to infrared index data for GLS glass we are pleased to release the full Sellmeier coefficients for GLS. Use of the following coefficient enables the refractive properties of GLS lenses to be modelled in most common lens design programs.
…ChAMP have been exhibiting all week at SPIE’s Defense and Commercial Sensing meeting in Baltimore with plenty of industry interest in the GLS family of glasses
In partnership with Artemis Optical, anti-reflection coating of GLS chalcogenide glass has been demonstrated. This reduces reflections from GLS glass surfaces to <1%, significantly lower than the ~28% reflection from the uncoated glass that is a result of its high refractive index. with Testing of the coated optics, shows them passing industrial standard adhesion, abrasion…
Presentations from the Infrared sensing and imaging : Challenges for next generation materials and devices meeting in Exeter on 15 November 2017 are now available
2d-material integration enabled by direct deposition of chalcogenide glass onto graphene is detailed in our latest Nature publication, in collaboration with MIT The deposited chalcogenides can be directly pattered on a variety of 2D materials to simultaneously act as passive light guides, active gates and protect the 2D material without the transfer processes previously used.

A new paper published 27 September 2017 by ChAMP partners from Oxford and Exeter continues the search for new “neuromorphic computing” architectures that mimic the brain’s approach to simultaneous processing and storage of information is intense.
