Tunneling-induced Talbot effect [PDF]

open access: yesScientific Reports, 2021
We investigate the reforming of a plane wave into a periodic waveform in its propagation through a structural asymmetry four-level quantum dot molecule (QDM) system that is induced by an inter-dot tunneling process and present the resulting tunneling ...

The space–time Talbot effect [PDF]

open access: yesAPL Photonics, 2021
The Talbot effect, epitomized by periodic revivals of a freely evolving periodic field structure, has been observed with waves of diverse physical nature in space and separately in time, whereby diffraction underlies the former and dispersion underlies ...

An Ultracompact Angular Displacement Sensor Based on the Talbot Effect of Optical Microgratings [PDF]

open access: yesSensors, 2023
Here, we report an ultracompact angular displacement sensor based on the Talbot effect of optical microgratings. Periodic Talbot interference patterns were obtained behind an upper optical grating. By putting another grating within the Talbot region, the

Experimental demonstration of passive microwave pulse amplification via temporal Talbot effect [PDF]

open access: yesScientific Reports, 2023
The temporal Talbot effect is a passive phenomenon that occurs when a periodic signal propagates through a dispersive medium with a quadratic phase response that modulates the output pulse repetition rate based on the input period. As previously proposed,

Talbot effect based sensor measuring grating period change in subwavelength range [PDF]

open access: yesScientific Reports
Talbot length, the distance between two consecutive self-image planes along the propagation axis for a periodic diffraction object (grating) illuminated by a plane wave, depends on the period of the object and the wavelength of illumination.
