What is the maximum differential group delay achievable by a space-time wave packet in free space?
Murat Yessenov, Lam Mach, Basanta Bhaduri +5
The group velocity of 'space-time' wave packets propagation-invariant pulsed beams endowed with tight spatio-temporal spectral correlations can take on arbitrary values in…
On the inverse problem of source reconstruction from coherence measurements
Andre Beckus, Alexandru Tamasan, Aristide Dogariu +2
We consider an inverse source problem for partially coherent light propagating in the Fresnel regime. The data is the coherence of the field measured away from the source. The reco…
Spatial coherence of fields from generalized sources in the Fresnel regime
Andre Beckus, Alexandru Tamasan, Aristide Dogariu +2
Analytic expressions of the spatial coherence of partially coherent fields propagating in the Fresnel regime in all but the simplest of scenarios are largely lacking and calculatio…
Incoherent lensless imaging via coherency back-propagation
Ahmed El-Halawany, Andre Beckus, H. Esat Kondakci +4
The two-point complex coherence function constitutes a complete representation for scalar quasi-monochromatic optical fields. Exploiting dynamically reconfigurable slits implemente…
Coherence measurements of scattered incoherent light for lensless identification of an object's location and size
H. Esat Kondakci, Andre Beckus, Ahmed El Halawany +3
In absence of a lens to form an image, incoherent or partially coherent light scattering off an obstructive or reflective object forms a broad intensity distribution in the far fie…
Basis-neutral Hilbert-space analyzers
Lane Martin, Davood Mardani, H. Esat Kondakci +7
Interferometry is one of the central organizing principles of optics. Key to interferometry is the concept of optical delay, which facilitates spectral analysis in terms of time-ha…
