Relevant experimental data of the beam splitter
The SPIE Digital Library offers a wide range of resources on beam splitters, focusing on their design, applications, and performance across various optical systems. The theory of the beam splitter (BS) in quantum optics is well developed and based on fairly simple mathematical and physical foundations. Abstract Beam splitters form very important components of quantum photonic devices and this chapter presents a quantum description of the beam splitter. Output states from beam splitters under different inputs such as single photons entering through one port, two photons entering through the two. Diagram of entangled photon generation: A pump beam induces type-I spontaneous parametric down-conversion (SPDC) in a nonlinear crystal, producing a polarization-entangled photon pair (signal and idler modes).
