Polarizing beam splitter
= Polarizing beam splitter
= Polarising beam splitter
{synonym}
A <polarizing beam splitter> sends two orthogonal <linear polarizations> to different output paths. Acting coherently on $\alpha|H\rangle+\beta|V\rangle$, it correlates path with <photon polarization> instead of measuring <photon polarization> unless a path is actually detected or discarded.
