Summary on Grant Application Form |

We will develop a number of original approaches (see above objectives) that will give rise to a new generation of all-fibre broadband photonics sources and promote major advances in non-intrusive medical imaging. Emphasis will be made on novel light sources for in vivo OCT imaging of cancer and ophthalmology. Continuous wave pumping of PCFs and HNLFs will allow broadband light generation around low-scattering and low absorption wavelengths of tissues. A new effect of CW-format pumped, cascaded Raman generation complemented by solitonic spectral spread in PCFs, originally suggested by the PI in 2003, is the basic effect behind the proposed research.All-fibre, broadband fibre sources will enable imaging around all relevant OCT wavelengths in the near-infrared, will allow to achieve routinely a micronscale resolution, will be capable of delivering 0.5-1W powers with ultra-low intensity noise. Challenges of engaging specific nonlinearities of PCFs at the OCT wavelengths, coherence properties analysis, efficient methods of spectral width and shape control will be proposed and investigated. An academic links of the PI with the world-leading OCT labs will provide a dynamic feedback on the research results and clinical trials potential.Additional adventurous spin-off research routes will be looked into, including feasibility of high power, pulsed and CW white light generation in 400nm to over 4pm range in all-fibre format; this may instigate major advances in fluorescence lifetime imaging of tissues, air-pollution control, non-intrusive detection of weapons applications.
