Fibre Bragg Gratings
Periodic structures within optical waveguides have long been recognised as being enabling devices for a whole host of applications in many areas of photonics.
The Fibre Grating Group has a long history of working with periodic devices and works on most aspects of periodic structures in optical fibres ranging from fundamental studies of photosensitivity in glasses, over device design and fabrication, to applications of gratings within telecommunication, fibre laser and sensing systems.
Our work covers most aspects of Bragg gratings and quasi phase-matching gratings in silica and non-silica fibres for pulse-shaping, filtering, wavelength conversion and switching applications. We also have activities on active devices including single-frequency Bragg grating fibre lasers, and periodically poled fibres for frequency-conversion and signal-processing applications. Additionally, we are working on design and analysis of low noise wide spectral bandwidth light sources for applications in ultrahigh resolution imaging systems.
The group has three laboratories within the ORC; two for device fabrication, and one for device characterisation and testing. We have a number of 1D and 2D high-precision airbearing stage systems up to 1m in length, and various continuous-wave and pulsed UV laser sources to facilitate writing of periodic structures in both standard silica as well as non-silica based fibres. We also have IR lasers for femto-second inscription of periodic index structures.
