Abstract
A composite all optical-fibre based tapered photonic waveguide () including a single or multiple secondary waveguides () within or around a primary waveguide () is described. The composite optical fibre may also be termed abeam tailoring optical fibre (BT Fibre) (). In use, at the larger secondary end () both the primary waveguide () and the secondary waveguide/s () may guide modes at a particular wavelength. However, at the same wavelength, adiabatically tapering down the waveguides () reduces the dimensions of the secondary waveguide/s () such that all the secondary waveguide/s () become effectively non-guiding at the smaller primary end (), whilst the primary waveguide () still guides. In other words, the composite optical fibre is a spatially modulating optical fibre ().
