Planar Optical Materials
The research group concentrates on the development of novel optoelectronic devices for applications in telecommunications, sensors and laser optics. Working closely with two University spin-outs (www.stratophase.com and www.covesion.com), we aim to develop advanced functionality devices by modifying and patterning standard optoelectronic materials.
The core of our technology lies in innovative control of materials using direct UV laser writing for waveguides and Bragg grating inscription, electrical poling technology for the creation of domain inverted ferroelectric materials and the deposition and processing of glass and silicon based materials. Working closely with the silica – fibre fabrication group we have pioneered new flat-fibre subtrates for integrated optics.
Specific project areas include the development of integrated chemical and biological sensors, creation of novel optoelectronic components for future advanced coding scheme networks, and microfluidic channel devices for opto-fluidic science.

Planar waveguide devices for WDM applications
In this project we are seeking to create new components for multi-wavelength telecom transmission systems which will use the inherent multiplex advantages of the planar geometry for high level integration. The work will involve fabrication, grating writing, optical experiments and design. The project will combine rf/microwave techniques with frequency control of lasers within signal processing gratings for next generation communications technology.
Development of periodically poled nonlinear optical materials for efficient frequency conversion into the visible, mid-infrared and terahertz
The aims of the project are to build on the existing, highly successful work on periodic poling of ferroelectric materials at the ORC and working with the University spin-out – Covesion Ltd. This is a technique for micro structuring nonlinear material to give excellent nonlinear properties. The project involves fabrication, testing and optical experiments. Specific applications include RGB sources for projection displays as well as applications in spectroscopy for gases and terahertz sources for materials characterisation.
Planar Grating sensors for biological and chemical detection
This work uses planar Bragg grating technology to create highly sensitive sensors for measurement of biological and chemical species. By adding specific binding elements (chemical groups and biological antibodies) onto a surface a high degree of specificity is obtained. The project will be collaborating closely with the University spin-out company Stratophase Ltd. Target applications include point of care diagnostics, field deployable chemical process control and oil/gas monitoring systems.
DLP Technology for adaptive optics
This area is looking at the application of DLP micro-mirror technology for applications in adaptive optics, laser control and image processing. Combining high levels of digital signal processing with state-of-the-art laser concepts it provides an exciting platform for next generation advanced optical engineering. Specifically the use of DLP controlled illumination in high performance microscopy and feedback in laser cavities will be studied.
Quantum lightwave circuits
The planar waveguide format based on UV written waveguides has been shown to be a powerful tool for investigating the fundamental quantum properties of light. With links to a number of world leading research groups we are collaborating on exciting projects in quantum information, single photon detection and atom optics. The project will involve waveguide device fabrication, theoretical modelling and optical experimental at our collaborators laboratories.
