Summary on Grant Application Form |

Neotronics Limited, the lead partner for this consortium have a requirement for integrated optics technology and advantages associated with multi-functional opto-hybrid devices for their instrumentation systems. The company wishes to make use of the small size and potential cost benefits associated with this technology for their portable gas detection systems. This will be achieved through the GEC-Marconi silica-on-silicon integrated optics technology combined with a number of grating functional elements for optical interconnects between waveguides and detectors. Using a broad light source, and waveguide gratings, will enable the multi-wavelength operation required for spectroscopic identification of the gas species via the hydrocarbon absorption NIR over-tones. Furthermore, a high level of sensitivity (~ppm level) can be achieved by exploiting in-plane Bragg scattering using surface relief gratings. The waveguides will include a polymer gas sensing layer (e.g. polysiloxane) in contact with the waveguide surface to allow evanescent field interaction. The source-coupled waveguide sensing system will be fully integrated with the Neotronics sensor evaluation system. The combination of partners in this programme is expected to develop a technology that will allow Neotronics to obtain a larger share of the sensor market internationally; GEC-Marconi and Oxford will benefit directly from the enabled technology.
