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.
We can model a photon going through the interferometer by assigning a probability amplitude to each of the two possible paths: the "lower" path which starts from the left, goes straight through both beam splitters, and ends at the top, and the "upper" path which starts from the bottom, goes straight through both beam splitters, and ends at the ...

The diffractive beam splitter [1] [2] (also known as multispot beam generator or array beam generator) is a single optical element that divides an input beam into multiple output beams. [3] Each output beam retains the same optical characteristics as the input beam, such as size, polarization and phase .
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.
The q-plate with topological charge q can generate a charge vortex based on the input beam polarization. An s-plate is a similar technology to a q-plate, using a high-intensity UV laser to permanently etch a birefringent pattern into silica glass with an azimuthal variation in the fast axis with topological charge of s.
