Although the theory and principles of optical waveguides have been established for more
than a century, the technologies have only been realized in recent decades. Optical …

We perform the in situ characterization, by second-order optical autocorrelation, of
femtosecond pulses transmitted by near-field optical probes. We demonstrate that …

The tunneling of evanescent waves into propagating waves is related to the convolution of
the high spatial frequencies of the source with those of the detectors. Such an approach is …

The existence of resonant enhanced transmission and the collimation of light waves by
subwavelength slits in metal films [for example, see Ebbesen, Nature (London) 391, 667 …

Self-collimation of tightly localized laser beams demonstrated in periodic media relies on a
perfect-matched rephasing of the Fourier constituents of the wavefield induced by a plane …

The problem of determining the achievable resolution in the reconstruction of a dielectric
object from the knowledge of its scattered field is dealt with. We face such problem for a two …

We show that a subwavelength nanometer-sized beam propagating without diffractive
broadening can be produced in free space by the constructive interference of multiple …

We simulate the early dynamics of enhanced light transmission through a subwavelength
metallic slit and find that the amplitude of the transmitted light can be modulated. To …

The super-resolution effects obtained by monochromatic evanescent waves are related to
many photon momentum cooperative effects reducing the propagation wavelength inversely …

The main optical phenomena obtained with materials having negative dielectric constant ϵ
and negative magnetic permeability μ are described by the use of geometric optics, and the …
