“…(4). We have previously shown that CGH type 2 is the best code when an ideal amplitude modulator is used 22 . In figure 2, we show the signal Fourier spectrum for each CGH type when an ideal amplitude modulator is simulated.…”

In this work we present the numerical analysis of fully complex fields employing computer generated holograms, implemented with a commercial amplitude liquid-crystal spatial light modulator (SLM). The hologram transmittance is obtained by adding an appropriate bias function to the real cosine computer hologram of the encoded signal. For the purpose of this work, we consider an appropriated bias function for a modulator in which the amplitude transmittance is coupled with a phase modulation. This type of coupled phase appears in a commercial Twisted Nematic Liquid Crystal Display (TNLCD), configured to provide amplitude modulation, with only two polarizers as external components. This modulation curve was experimentally obtained and adjusted to a mathematical function. The numerical evaluation is done by calculating the signal to noise ratio of the reconstructed complex fields for the real modulation curve. Results show that for a good behavior for complex fields a constant bias function should be implemented. As a particular interesting case we generate propagation invariant complex beams with high accuracy and simplicity.

“…In previous work, we studied the performance of a SLM whose amplitude modulation is coupled with a lineal phase modulation 22 . We shown that CGHs designed with the first bias function (given by the soft envelope of the signal modulus) perform better if the range of the coupled phase is below some critical value.…”

We propose a scheme to split a cloud of cold non-interacting neutral atoms based on their dipole interaction with a single structured light beam which exhibits parabolic cylindrical symmetry.Using semiclassical numerical simulations, we establish a direct relationship between the general properties of the light beam and the relevant geometric and kinematic properties acquired by the atomic cloud as its passes through the beam.
