We investigate the spatial coherence of the light generated from high-power multi-chip red LEDs by using the van Cittert-Zernike theorem. It is theoretically demonstrated that the light generated from...
Tight Focusing of Light Beams: Effect of Polarization, Phase, and Coherence
Tight Focusing Light Beams Effect of Polarization Phase Coherence

The focusing theory of electromagnetic waves has been well developed. A scalar wave theory satisfactorily describes the focusing process for a small semi-aperture angle. However, the vectorial charact...
