Abstract Higher orders of orbital angular momentum states (OAMs) of light have been produced with a double-pass configuration through a zero-order vortex half-wave retarder (VHWR). This double-pass technique can reduce the number of VHWR plates used,

In a prior report the optical vortex was characterized using the near-field Talbot effect (Panthong et al 2016 J. Opt. 18 035602; Panthong et al 2018 Appl. Opt. 57 1657). This near-field technique can resolve both order and charge of the orbital angu

We present an alternative explanation of near-field and far-field diffraction, i.e., the Talbot effect and single- and double-slit experiments, with the same expressions. Our method is based on the superposition of waves with different path lengths.

The interference contrast in a near-field diffraction pattern can be improved using an asymmetric grating with a small grating window. However, commercial asymmetrically shaped gratings are not available. Here, we report a method that overlaps two gr

We apply the near-field Talbot effect to distinguish, characterize, and detect optical vortices. We perform experiments with single-, double-, multiple-slit, and grating diffraction. High-contrast image detection is achieved with the Talbot effect of

We study the Talbot interferometry with an additional mask grating located behind the diffraction grating. The self-imaging so-called, Talbot carpet, can be very sensitive to an external perturbation. We here show the measurement and the optimization

A simplified explanation of near-field and far-field diffraction with matter-wave is described using the path integral formulation. Our approach is demonstrated with cold Rb atoms in single-, double-, and multiple-slit configurations. With the use of
