We report the development of an optical fibre probe which could find use as an aid for margin detection during surgery. A fluorophore doped polymer is coated on an optical fibre tip, allowing for pH values of unknown tissue to be measured and compare

The development of a fast and reliable whispering gallery mode (WGM) simulator capable of generating spectra that are comparable with experiment is an important step forward for designing microresonators. We present a new model for generating WGM spe

A method for determining the diameters and shell thicknesses of microbubble resonators is presented; it entails simulating whispering gallery mode (WGM) spectra using a newly developed finite-difference time-domain (FDTD)-based toolkit. Spectra for a

Incomplete removal of malignant tumours continues to be a significant issue in cancer surgery. It increases the risk of local recurrence and impaired survival, and results in the need for additional surgery with associated attendant costs and morbidi

We demonstrate the use of a portable optical setup based on polymer coatings on the tip of an optical fibers that is capable of differentiating between tumorous and healthy tissue in human samples by probing the extracellular pH of the surface.

Intraoperative detection of tumorous tissue is an important unresolved issue for cancer surgery. Difficulty in differentiating between tissue types commonly results in the requirement for additional surgeries to excise unremoved cancer tissue or alte

We derive a unified model for calculating the power spectrum and resonance positions of multilayer microsphere resonators. The model may include a dipole in any layer, or a uniform distribution of dipoles resembling an active layer.

Whispering gallery modes (WGMs) have been widely studied over the past 20 years for various applications, including biological sensing. While the WGM-based sensing approaches reported in the literature have shown tremendous performance down to single

We examine the fluorescence sensing efficiency of suspended-core fibres (SCFs), and multi-mode fibres (MMFs). Theoretical and experimental results show that the SCFs display a consistently higher signal than MMFs with equivalent conditions. Refereed/

Microstructured optical fibers, particularly those with a suspended-core geometry, have frequently been argued as efficient evanescent-field fluorescence-based sensors. However, to date there has not been a systematic comparison between such fibers a
