Can beam splitters be connected in parallel instead of in series
For beam splitters with two incoming beams, using a classical, lossless beam splitter with Ea and Eb each incident at one of the inputs, the two output fields Ec and Ed are linearly related to the inputs through where the 2×2 element is the beam-splitter transfer matrix and r and t are the and along a particular path through the beam splitter, that path being indicated by the subsc.
