Record type: Conference or Workshop Item (Other)


Photonic technologies are revolutionising our access to chemical and biochemical information, driven by the demand for fast, low-cost, automated chemical analysis in a multiplicity of applications from food safety, water quality, security, personal and preventative medicine and rapid point-of-care diagnostics. The scale of integration, low cost and robustness of the microfabrication approaches which have enabled the pervasiveness of consumer electronics are expected to enable widespread deployment of chemical and bioanalytical microsystems. Optical techniques have traditionally played a major role in quantitative chemical analysis and remain the mainstay of detection in “lab-on-chip” systems, but the degree of optical functionality integrated within these systems remains limited, and they have yet to benefit fully from the massive growth in optical telecommunications technologies in recent decades. Biosensor and lab-on-chip research and commercialisation have both also been hampered by the lack of integrated photonic platforms which can operate over both the near-infrared (NIR) spectral region at wavelengths from about 0.7µm to 2µm and the mid-infrared (MIR) region from about 2µm to 20µm, which would enable new opportunities for sensitive, selective, label-free biochemical analysis. Progress on optofluidic integration for a “lab-on-chip” platform and on new materials and approaches for high-sensitivity waveguide evanescent spectroscopies in the NIR and MIR will be described.
