Discriminating between Coherent and Incoherent Light with Planar Metamaterials

Incoherent Digital Holographic Microscopy with Coherent and Incoherent Light

Holography is an attractive imaging technique as it offers the ability to view a complete three-dimensional volume from one image. However, holography is not widely applied to the regime of fluorescence microscopy, because fluorescent light is incoherent and creating holograms requires a coherent interferometer system. We review two methods of generating digital Fresnel holograms of threedimens...

Coherent Energy Transfer under Incoherent Light Conditions.

Recent two-dimensional electronic spectroscopy (2DES) experiments have reported evidence of coherent dynamics of electronic excitations in several light-harvesting antennae. However, 2DES uses ultrafast coherent laser pulses as an excitation source; therefore, there is a current debate on whether coherent excitation dynamics is present under natural sunlight - incoherent - illumination conditio...

Coherent addition of spatially incoherent light beams.

We report on efficient coherent addition of spatially incoherent multimode laser beam distributions. Such addition is demonstrated within a multi-channel laser resonator configuration, obtaining more than 90% combining efficiency while preserving the good beam quality. We explain the rather surprising physical phenomenon of coherently adding spatially incoherent light by self-phase-locking of e...

Distinguishing between Coherent and Incoherent Texts

In this paper, I show that current discourse theories are not able to explain why different orderings of the same textual segments exhibit different properties with respect to coherence. I then propose a criterion of coherence that exploits both the strong tendency of textual units that are associated with certain rhetorical relations to obey a canonical ordering and the inclination of semantic...
