A diffractive beam splitter can generate either a 1-dimensional beam array (1xN) or a 2-dimensional beam matrix (MxN), depending on the diffractive pattern on the element. The diffractive beam splitter is used with monochromatic light such as a laser beam, and is designed for a specific wavelength and angle of separation between output beams.

The fiber optic splitter is one of the most important passive devices in the optical fiber link. It is an optical fiber tandem device with many input and output terminals, especially applicable to a passive optical network ( EPON , GPON , BPON , FTTX , FTTH etc.) to connect the main distribution frame and the terminal equipment and to branch ...
A Pockels cell, by design, is a capacitor, and often require high voltages to change the state of the polarization of the laser beam to effectively operate as a switchable waveplate. The voltage required depends on the type of Pockels cell, the wavelength of the light, and the size of the crystal; but typically, the voltage range is in the ...
The output depends on the polarization of the input. Suppose polarization axes x and y parallel with the slow and fast axis of the waveplate: Composition of two linearly polarized waves, phase shifted by π/2. The polarization of the incoming photon (or beam) can be resolved as two polarizations on the x and y axis.
A stack of plates at Brewster's angle to a beam reflects off a fraction of the s-polarized light at each surface, leaving a p-polarized beam. Full polarization at Brewster's angle requires many more plates than shown. The arrows indicate the direction of the electrical field, not the magnetic field, which is perpendicular to the electric field.
Changing the beam splitter phases can change the classical result to arm d or a mixture of both, but the quantum result is independent of these phases. For a more general treatment of the beam splitter with arbitrary reflection/transmission coefficients, and arbitrary numbers of input photons, see the general quantum mechanical treatment of a ...
