Silica fibre facility

About the Silica fibre facility

Part of the Zepler Cleanrooms

We specialise in the manufacture and research of doped and structured fibres. 网络彩票APP下载_澳客彩票网-官方游戏, equipment includes fibre towers and modified chemical vapor deposition (MCVD) lathes. We also house a range of preform and fibre characterisation tools.  

We produce industry-standard passive and active preforms and fibres. We also manufacture specialist fibres with complex structures, for example hollow core fibres. This enables research into high-power fibre lasers and advanced telecommunications and sensing devices.

?Complete post-processing and characterisation of silica fibre includes:

  • preform and fibre index profilers
  • fibre proof-testing 
  • high-resolution optical time domain reflectometry (OTDR)

Highlights

  • we produce a range of fibre types including ribbon, spun, bundle and microstructured. We also produce fibres with dimensions in the 50 to 1500 micrometre (μm) range  
  • features of our drawing tower include both conventional thermal and ultra-violet (UV) cured polymers, as well as novel high temperature UV cured polymers and novel dynamic preform spinning  
  • we use well-established outside vapor deposition (OVD) technology to explore high-volume fabrication of rare-earth doped glasses
  • we use MCVD in-situ solution doping and vapour phase techniques. This allows us to create next generation rare-earth doped fibres for high power lasers
  • low loss hollow core fibre fabrication. Against conventional technology, we see lower losses at telecommunications wavelengths. We achieve similar in the UV, visible and mid-infrared
  • 10 kilometre continuous draw of low-loss, uniform lengths of hollow core fibre?

Technical specification

Equipment 

The facility occupies over 160m2 of ISO 7 (class 10,000) cleanroom space and includes:

  • 2 custom MCVD lathes including a chelate delivery system for passive and active preform fabrication 
  • glass working lathe for glass joins and processing  
  • an ISO 5 (Class 100) preparation area for microstructured preform fabrication
  • dedicated chemical preparation areas for glass etching
  • OVD system  
  • support for a wide variety of dopants with both gas phase deposition and advanced solution doping techniques for active fibre fabrication
  • comprehensive glass or preform post-processing facilities including ultra-sonic drilling or milling
  • 10 metre (m) state-of-the-art, dual-sided fibre draw tower, one side of which is dedicated to and tailored for hollow core fibre production
  • fibre proof test capability
  • full preform and fibre analysis capability including index profiling, tomography, stress measurement, OTDR and rare earth spectroscopy
  • optical measurement facilities for complete fibre performance evaluation as well as laser/amplifier and/or device level characterization in both active and passive fibres 
  • extrusion capability for soft glass microstructure fibres 
  • 4m compound (soft) glass drawing tower, tailored for making non-silica based solid and hollow core fibres, is also available in the novel glass facility  

We also offer a range of fabrication, characterisation, design, and simulation services.?
