We describe a novel fundamental optical phenomenon and report on experimental progress towards its verification.
The Geometric Spin Hall Effect of Light amounts to a multiple wavelengths shift of a light beam’s position [A. Aiello et. al., Phys Rev Lett 103, 100401 (2009)]. This displacement depends on the properties of the light beam such as the state of polarization and the geometry of the detection system.
The effect occurs whenever a projection is perfomed on the light field which breaks the symmetry of the beam’s internal structure. We show that a suitable projection can be implemented using a tilted polarizer. A setup using a commercial polarizer in a configuration suitable to measure the predicted shift will be discussed.
