WebTapered multimode interference (MMI) couplers have been broadly studied for applications in integrated photonic circuits due to their footprints being smaller than conventional MMIs. The operation of an MMI is fundamentally related to the Talbot effect. In this Letter, the Talbot effect is analyzed in cylindrical coordinates, rather than conventional Cartesian … Web20 Nov 2024 · The Talbot effect for the optical vortices in the visible range is experimentally observed and the respective Talbot carpets for the optical vortices are experimentally …

Web31 Jan 2011 · The Talbot effect is observed when, under appropriate conditions, a beam of light is reflected from (or transmitted through) a periodic pattern. The pattern may have one-dimensional periodicity (as in traditional gratings), or it may exhibit periodicity in two dimensions (e.g., a surface relief structure or a photographic plate imprinted with identical … WebThe Talbot effect (or the self-imaging effect) can be observed for a periodic object with a pitch larger than the diffraction limit of an imaging system, where the paraxial approximation is applied. ... (MMI) stack. As long as the loss of the metamaterial is small enough, deep subwavelength image size can be obtained in the super Talbot effect ... sharp 39 software
Spectral self-imaging of optical orbital angular momentum modes
The Talbot effect is a diffraction effect first observed in 1836 by Henry Fox Talbot. When a plane wave is incident upon a periodic diffraction grating, the image of the grating is repeated at regular distances away from the grating plane. The regular distance is called the Talbot length, and the repeated images are … See more Due to the quantum mechanical wave nature of particles, diffraction effects have also been observed with atoms—effects which are similar to those in the case of light. Chapman et al. carried out an experiment in which … See more The nonlinear Talbot effect results from self-imaging of the generated periodic intensity pattern at the output surface of the See more • Angle-sensitive pixel See more The optical Talbot effect can be used in imaging applications to overcome the diffraction limit (e.g. in structured illumination fluorescence microscopy). Moreover, its … See more • Talbot's 1836 paper via Google Books • Rayleigh's 1881 paper via Google Books • Undergraduate thesis by Rob Wild (PDF) • Talbot effect observed over space-time for the first time See more WebThe Talbot-effect is a near field ‘self-imaging’ effect generic for certain wave equations like the paraxial wave equation and the Schrödinger equation. Any spatial modulation of period Λ of a plane carrier wave is reproduced after the Talbot-length zR = 2Λ 2 /λ. Moreover, starting with a pure phase modulation in a certain plane, after ...
