GLS refractive index vs. wavelength
We have recently obtained new infrared ellipsometry data for our Gallium Lanthium Sulphide glass giving more accurate refractive index measurements to 10um. If you would like more detailed n or k data in this spectral region please contact us. The latest data sheet also has updates on the physical and optical propoerties of GLS Chalcogenide glass.
As part of the Glass Reflections Conference ChAMP are orgainising a one day workshop on Chalcogenides on 9 September 2015 at Murray Edwards College, University of Cambridge.
To attend please register with the day rate for the Chalcogenide workshop or you are also of course welcome to attend the entire conference, which runs from 7 – 9 Sept
Computers that function like the human brain, using optical fibres made of chalcogenide glass, could become a reality according to new research.
A key focus of Champ is to continue the work conducted under the EPSRC Centre for Innovative Manufacturing in Photonics on reducing contamination and impurities in Chalcogenide glass. A long-term focus on purifying raw materials and optimising the manufacturing process has led to a signficant reduction in oxide and water impurities. This has yielded a 100x fold reduction in transmission loss at 5um and a signficant extension of the operating band edge to >10.5um, as shown, removing the path to applying chalcogenides in many applications.
Note there is no offset applied in these loss figures– the curve shown are a true reflection of the glass loss and the improvements made.
If you weren’t able to make the ChAMP Partnership day on 9 March 2015, this short video will give you a flavour of the atmosphere.
Presentations and posters from the day are now also available giving an overview of the latest developments and impact of Chalcogenide research and development
Combining with the Photonex Southampton exhibition, brought 231 people to the CHAMP partnership day on 9 March to mark the launch of the project to advance the manufacture of Chalcogenide glasses and demonstration their applications – a record breaking audience for such an event at Southampton.
Prof Brian Hayden explaining the potential of hIgh throughput screen of advanced material compositions and how it can be applied to Chalcogenides
Talks from the work package leaders at Southampton, Heriot-Watt, Exeter, Oxford and Cambridge Universities were welcomed by an audience including over 100 representatives from across UK industry. Industrial partners also provided valuable insights into how these glasses can be processed and what is driving their adoption in both passive and active applications.
Presentations from the day will be posted here shortly.
ChAMP would like to thank partners,presentors, exhibitors and all the University and Xmark Media staff who made the day such a sucess.
