Slow light beam splitter.
We demonstrate a slow light beam splitter using rapid coherence transport in a wall-coated atomic vapor cell. We show that particles undergoing random and undirected classical motion can mediate coherent interactions between two or more optical modes. Coherence, written into atoms via electromagnetically induced transparency using an input optical signal at one transverse position, spreads out ...
متن کاملQuantum measurements with an amplitude-squeezed-light beam splitter.
Quantum measurement of amplitude fluctuation is performed by the injection of 2.5-dB amplitude-squeezed light produced by a quantum-well laser into the dark port of a beam splitter as the meter wave. It is shown that the measurements satisfy the criteria of quantum nondemolition measurement. The measured transfer coefficient and the quantum-state preparation ability are 1.07 and 0.8, respectively.
متن کاملBeam Splitter Input-Output Relations
The beam splitter has played numerous roles in many aspects of optics. For example, in quantum information the beam splitter plays essential roles in teleportation, bell measurements, entanglement and in fundamental studies of the photon. Electric fields E1 and E2 enter input ports 1 and 2, respectively. Field 1 evolves as E1 → TE3 + RE4, where T,R are the transmission and reflection coefficien...
متن کاملParallel-slab polarizing beam splitter and photopolarimeter.
A dielectric-slab polarizing beam splitter (PBS) is described that generates two parallel beams of orthogonal p and s linear polarizations in reflection and functions as a diattenuator in transmission. The plane-parallel slab, which is set at Brewster's angle, is uncoated on one side and has an s-polarization antireflection coating (s-ARC) on the other side. Analytical results are presented for...
متن کاملMagneto-optical beam splitter for atoms.
We report an experimental demonstration of diffraction of He* atoms from a magneto-optical grating. The grating was produced by the interaction of three-level atoms with a light field of spatially varying polarization and a magnetic field. For a light shift matched to the Zeeman shift. a two-peaked diffraction pattern was observed. corresponding to a momentum splitting of 42hk. The effect of ch...
