Gratings and Slow Light
Fibre
Bragg gratings are written into both conventional
and chalcogenide glass fibres/waveguides
using novel interferometric side-write
technique developed in house.
A fully flexible grating
writing system allows for complex grating
fabrication (apodisation, chirp) using
high power UV (244 nm) and green (532
nm) laser sources aligned to the interferometric
apparatus.
A combined Swept Wavelength
and Dispersion Measurment System is used
to measure reflection, transmission and
in dispersion in the fibre Bragg gratings
in the C-band (1520-1570).
