We report the implementation of a highly sensitive tunable beam displacer based on the concept of weak value amplification, that allows to displace the centroid of a Gaussian beam a distance much smaller than its beam width ...

Entangled photons are generally collected by detection systems that select their certain spatial modes, for example using single-mode optical fibers. We derive simple and easy-to-use expressions that allow us to maximize ...

We report the implementation of a tunable beam displacer, composed of a polarizing beam splitter(PBS) and two mirrors, that divides an initially polarized beam into two parallel beams whose separation can be continuously ...
