We will develop and investigate a new type of programmable slow light materials where the speed of light is reduced by up to five orders of magnitude. Structuring matter at the microand nanoscale has for several years created new types of materials. In this project, with the help of programmable atoms, materials are structured in frequency-space instead of physical space. In this way materials and devices with unique properties can be created. We will investigate fundamental concepts to best optimize and employ the slow light effects, develop and improve the materials and target new applications. The potential of these materials to incite game-changing technological breakthroughs will be assessed for two very different applications – ultra stable optical oscillators and medical diagnostics and treatment schemes using optical techniques. Effects on slow light occurring due to mechanical influence from local strain gradients will be investigated by direct molecular dynamic simulations supplemented by pertinent atomic interaction potentials. Such effects have not previously been predicted or modeled and can strengthen basic research in nanomechanics and establish firm links to fundamental atomic physics.
