Beamsplitters are fundamental components in optical engineering, serving to precisely divide a single input beam of light into two distinct output beams. This division allows for the simultaneous analysis or utilization of the light's properties along two separate paths. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux). Output states from beam splitters under different inputs such as single photons entering through one port, two photons entering through the two. Normally, you would want to place a beam splitter at 45 degrees with respect to the input beam. Like this: Now, I want to know what happens to the angles of the output beam when the cube is not aligned to the optical. Beam splitters are used to manipulate and control light, making them valuable devices in both classical and quantum optics.
