摘要:
The design, fabrication and experimental characterisation of surface-relief gratings in single-mode optical fibres are described. Novel structures employing high-refractive-index over-layers are discussed with which reflectivities up to 98% and linewidths down to 0.8 nm at the first-order Bragg wavelength have been achieved. Applications of these structures are described.

摘要:
A single-mode optical-fibre switch which is electrically activated has been fabricated. This device is achieved by forming two couplers in series on a pair of single-mode optical fibres to provide a compact Mach-Zehnder interferometer (MZI). Power switching in the output arms is achieved by introducing a phase shift or path difference in the MZI by various means. The application of the device as a wavelength-selective switch is also considered.
