  • Why does the beam splitter have a weak current

    Why does the beam splitter have a weak current

    A beam splitter reflects some of the infrared light and lets the rest pass through. This creates two separate paths, which later overlap and interfere. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. Together, they decide just how accurately an instrument captures those unique infrared “fingerprints” from different substances. To study the behavior of their strong mode mixing dynamics, we consider variable beam splitters and their dynamics using Wigner's phase space distribution, W, the evolution of which is governed by the continuity. Beam splitters allow us to superpose two continuous single mode quantum systems.
