Measuring light's twist

Light carries an orbital angular momentum in addition to, and independent, of photon spin. Whereas the spin angular momentum (polarization) has only two orthogonal states, the orbital angular momentum has any number. To use this extra information we present a multi-way beam splitter to efficiently s...

Zusammenfassung:Light carries an orbital angular momentum in addition to, and independent, of photon spin. Whereas the spin angular momentum (polarization) has only two orthogonal states, the orbital angular momentum has any number. To use this extra information we present a multi-way beam splitter to efficiently separate individual photons according to their orbital angular momentum.
