WebDiscrete plasmonic Talbot effect in the subwavelength metal waveguide arrays (SMWAS) is theoretically analyzed and numerically simulated. Based on the finite-difference time-domain technique, we discuss the influence of the … WebMar 15, 2008 · We discuss the discrete Talbot effect in one- and two-dimensional waveguide lattices under the influence of an external potential. It is shown that the field recovery can be precisely tuned by changing the gradient of the potential. ... It turned out, that waveguide arrays possess unique imaging [2] and propagation [3] properties, …

WebDec 1, 2024 · Recently, we have study the discrete Talbot effect and subwavelength focusing in MWGAs [15], [16], where the supermode theory of SPPs is put forward to explain these phenomena. In this paper, we propose all-optical logic gates based on MWGAs. The supermode theory of SPPs mentioned in Refs. [15], [16] is used to guide the design of … WebAbstract:We theoretically study discrete Talbot self-imaging in hexagonal, square, and irregular two-dimensional waveguide arrays. Different from its counterpart in a continuous system, the periods of the input fields must belong to {1, 2, 3, 4, 6} for Talbot self-imaging. dailymotion 2022

WebJan 1, 2013 · The optical power splitter base on multimode interference waveguide has been proposed [9], [10], [11]. Iwanow et al. explored discrete Talbot revivals in one-dimensional waveguide arrays [12]. Self-imaging phenomena in periodic dielectric waveguides have been predicted and investigated based on multimode interference … WebJan 1, 2013 · The coupling characteristics of the finite waveguide arrays are analyzed by taking into account the coupling between the non-adjacent waveguides. The sufficient condition to achieve Talbot effect in the waveguide arrays is discussed. The results show that the condition is more rigorous than that obtained by only considering adjacent coupling.
