We present experimental results on photosensitive post-tuning the dispersion of a two-dimensional photonic crystal waveguide made from chalcogenide glass. A 5 nm shift of the resonant wavelength is reported.
We demonstrate the detection of proteins utilizing fluorescent nanocrystals within an optical fibre. The protein concentration within an aqueous solution inside a soft glass microstructured optical fibre is measured using a new fluorescence capture sensing approach.
We have developed a technique for creating high quality tellurite microspheres with embedded nanodiamonds (NDs) containing nitrogen-vacancy (NV) centres. This hybrid method allows fluorescence of the NVs in the NDs to be directly, rather than evanescently, coupled to the whispering gallery modes of the tellurite microspheres at room temperature. As a… (More)
We have investigated the vortex modes in suspended core fiber with Comsol simulations. The simulation results show that this class of structured fibre is well suited to support stable propagations of the LP11 modes.
