The Spin Optics laboratory studies the spin currents induced by light in semiconductor structures. We work with exciton-polaritons: mixed light-matter quasi-particles, which obey bosonic statistics and can form condensates and coherent fluids. Polariton spin currents are expected to form a basis of a new set of logic devices, where information would be encoded by spin or polarisation. We aim at controlling the polariton spins on a picosecond timescale, which would allow encoding of information on a terahertz frequency. The experimental facilities currently available in the Spin Optics laboratory include:

• time- and spatially resolved Faraday and Kerr rotation spectroscopy;

• spin noise spectroscopy;

• angular resolved photoluminescence, reflectivity and Raman spectroscopy;

• time-resolved magneto-photoluminescence.

• Terahertz spectroscopy

The Spin Optics laboratory strongly collaborates with the world-leading research centers, including:
