Peter Smith (Professor, ORC Southampton) develops integrated photonic devices for quantum technologies and sensing. Research: (1) direct UV laser writing — waveguides and Bragg gratings in silica/glass for atom-trap integrated optics; (2) quantum photonic circuits — integrated waveguides for quantum computing and communication; (3) PPLN and nonlinear optics — electrical poling of LiNbO₃ for wavelength conversion (Covesion spinout); (4) integrated sensing — chemical/biological sensors and optofluidic microfluidic chips; (5) applications to cold atom systems — 'Integrated optical elements for miniaturised atom traps'. Spin-outs: Covesion, Stratophase.
