Fibre Bragg gratings fabrication in four core fibres [PDF]
Due to the limitation of the lens effect of the optical fibre and the inhomogeneity of the laser fluence on different cores, it is still challenging to controllably inscribe different fibre Bragg gratings (FBGs) in multicore fibres. In this article, we reported the FBG inscription in four core fibres (FCFs), whose cores are arranged in the corners of a

Improved design of a DFB Raman fibre laser [PDF]
A Raman fibre laser based on phase shifted DFB structures is modelled for the first time. Using parameters of realistic devices, the model predicts low-threshold and highly-efficient laser output.

Long continuously chirped fibre Bragg gratings for compensation of linear- and 3rd order-dispersion
For the first time long broadband chirped fibre Bragg gratings with a dispersion profile designed to compensate 3rd order-dispersion are presented. These results demonstrate how the increased demands for dispersion compensation at very high bit-rates can

Fibre Bragg gratings and their applications [PDF]
Summary form only given. Optical fibre Bragg gratings are the most significant new fibre device since the EDFA and will have a major impact on the design and implementation of future optical networks. Applications include single and multichannel add/drop filters, EDFA gain stabilising and spectrum flattening filters, dispersion compensation, as well as

Grating formation in BGG31 glass by UV exposure [PDF]
A three-dimensional index variation grating in bulk BGG31 glass written using neither hydrogen loading nor germanium doping is demonstrated. This material is useful for fabricating ion-exchanged waveguides, and its photosensitivity to ultraviolet (UV ...

Growth Characteristics of Fiber Bragg Gratings Fabricated in High Germania Boron Co-Doped Fiber
This paper reports and provides an explanation for the growth characteristics of fibre Bragg gratings (FBGs) fabricated in high germania boron co-doped optical fiber by using a continuous wave (CW) doubled frequency Argon ion laser as an UV light source.
