Four-photon interference with asymmetric beam splitters.
Two experiments of four-photon interference are performed with two pairs of photons from parametric downconversion with the help of asymmetric beam splitters. The first experiment is a generalization of the Hong-Ou-Mandel interference effect to two pairs of photons while the second one utilizes this effect to demonstrate a four-photon de Broglie wavelength of lambda/4 by projection measurement.
متن کاملOn the Optimum Design for 1xN Multimode Interference Coupler based Beam Splitters
An analytical formula for optimum 1xN multimode input/output channel width is derived for improved performance based on the insertion loss and output uniformity. Experimental investigation of a SOI based 1x12 MMI confirms the analytical results. ©2010 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (130.2790) Guided waves
متن کاملCarbon nanotubes as cooper-pair beam splitters.
We report on conductance measurements in carbon nanotube based double quantum dots connected to two normal electrodes and a central superconducting finger. By operating our devices as beam splitters, we provide evidence for crossed Andreev reflections tunable in situ. This opens an avenue to more sophisticated quantum opticslike experiments with spin entangled electrons.
متن کاملQuantum optics of lossy asymmetric beam splitters.
We theoretically investigate quantum interference of two single photons at a lossy asymmetric beam splitter, the most general passive 2×2 optical circuit. The losses in the circuit result in a non-unitary scattering matrix with a non-trivial set of constraints on the elements of the scattering matrix. Our analysis using the noise operator formalism shows that the loss allows tunability of quant...
متن کاملEtched beam splitters in InP/InGaAsP.
An etched beam splitter (EBS) photonic coupler based on frustrated total internal reflection (FTIR) is designed, fabricated and characterized in the InP/InGaAsP material system. The EBS offers an ultra compact footprint (8x11 μm) and a complete range of bar/cross coupling ratio designs. A novel pre-etching process is developed to achieve sufficient depth of the etched coupling gaps. Fabricated ...
