Diffraction-free space-time beams
H. Esat Kondakci, Ayman F. Abouraddy
Diffraction-free optical beams propagate freely without change in shape and scale. Monochromatic beams that avoid diffractive spreading require two-dimensional transverse profiles,…
Interferometric control of the photon-number distribution
H. Esat Kondakci, Alexander Szameit, Ayman F. Abouraddy +2
We demonstrate deterministic control over the photon-number distribution by interfering two coherent beams within a disordered photonic lattice. By sweeping a relative phase betwee…
Compressive optical interferometry
Davood Mardani, H. Esat Kondakci, Lane Martin +2
Compressive sensing (CS) combines data acquisition with compression coding to reduce the number of measurements required to reconstruct a sparse signal. In optics, this usually tak…
Demonstration of an optical-coherence converter
Chukwuemeka O. Okoro, H. Esat Kondakci, Ayman F. Abouraddy +1
Studying the coherence of an optical field is typically compartmentalized with respect to its different optical degrees of freedom (DoFs) -- spatial, temporal, and polarization. Al…
Transparent Perfect Mirror
Ali K. Jahromi, Soroush Shabahang, H. Esat Kondakci +3
A mirror that reflects light fully and yet is transparent appears paradoxical. Current so-called transparent or "one-way" mirrors are not perfectly reflective and thus can be disti…
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…
