Beam splitters find applications for interferometers, auto correlators, cameras, projectors and laser systems. There are plate, cube, pellicle and polka dot Beam splitters. The beam splitter adds to the growing catalog of devices being created for future photonic computing. A beam splitter that consists of a glass plate with a reflective dielectric coating on one side gives a phase shift of 0 or π, depending on the side from which it is incident. Transmitted waves have no phase shift. Reflected waves entering from the reflective side are phase-shifted by π, whereas reflected waves entering from the glass side have no phase shift. Standard beam splitters are designed to split incident light at a specific Reflection/Transmission (R/T) ratio that is independent of polarization state.
