(2000-11-01)Structures that cause colour or provide antireflection have been found in both living and extinct animals in a diversity of forms, including mirror-reflective and diffractive devices. An overview of this diversity is ...
-
(1999-03-01)A 64 channel optical array interconnect based on 125 µm polymer optical fibres arranged in an 8×8 array with dimensions of 2×2 mm2 is presented. Typical insertion losses of 1.5 dB (660 nm) and 5 dB (980 nm) over a 20 cm ...
-
(2000-11-01)The concepts of interferometry employed in the production of rings of equal chromatic order are applied to calculations of layer thicknesses forming alternate periods in multilayer systems. The achromatic combination of ...
-
(2000-03-01)This paper describes the mathematical results of an investigation into the design of a rotating mirror for use in a laser-scanning display. The main design parameter considered in this work was the scan linearity. Using ...
-
(2000-09-01)Le présent article développe une analyse formelle de la technique des tavelures obscures, notamment en ce qui concerne l'effet dû à la taille finie des pixels. Les lois de probabilité à fort flux sont d'abord évaluées. ...
-
(1999-09-01)We present an analytic simplified form for the 4 × 4 propagation matrix of a general homogeneous biaxial layer. The expression is applicable to any linear homogeneous, absorbing, biaxial, gyrotropic, magneto-optic, arbitrarily ...
-
(1999-03-01)The linear birefringence induced in a crystal by the first power of an applied electric field E - the Pockels effect - is traditionally described by the index ellipsoid model and the impermeability tensor. An alternative ...
-
(1999-11-01)The design for an annular-aperture uniform-axial-intensity diffractive axicon illuminated by a Gaussian beam is given. The stationary phase method and a numerical calculation are applied to investigate the characteristics ...
-
(1999-09-01)An optical drill is proposed for the nanofabrication of three-dimensional (3D) (diamond-like) lattices in positive photoresists, thereby opening a way towards 3D photonic crystals at optical wavelengths. Basically, an ...
-
(1999-09-01)The theory of an optical limiter-discriminator using a pair of laser diodes synchronized to the incoming signal is developed. The frequency sensitivity of this limiter-discriminator is fairly high compared with other ...
-
(1999-03-01)We present the architecture for a multichannel parallel correlator to apply a set of Gabor filters to the input image simultaneously. The basic features are: (a) a liquid crystal spatial light modulator displays the input ...
-
(1999-03-01)Communication between computing systems is now recognized as posing the main limitation to increasing the speed of all electronic systems beyond levels currently achieved in existing supercomputers. Optical interconnects ...
-
(1999-03-01)In this paper an application of optical signal and energy transmission in the field of biotechnology is presented: a retinal implant, which is powered and provided with digitally coded information simultaneously by free-space ...
-
(1999-07-01)The width L of the first Bragg scattering peak in the (111) direction of a face-centred cubic lattice of air spheres can be well approximated by a simple formula which only involves the volume averaged and 2 over the ...
-
(1999-09-01)We calculate the linear optical response of island films, considering, in particular, a statistical character of the geometry of the cluster assembly as well as electromagnetic interaction between the clusters in the film. ...
-
(2000-05-01)Polarization decay of linearly polarized light propagating in a multiply scattering isotropic medium with embedded model inhomogeneity (absorbing half-plane) is studied experimentally and by means of Monte Carlo simulation. ...
-
(1999-07-01)We employ asymptotic methods to speed up the computation of fields in the focal region of diffractive lenses (DLs). Each DL is treated locally as a linear grating with slowly varying period and groove orientation. Rigorous ...
-
(2000-07-01)It has been possible to excite a spatial soliton in a dye doped liquid crystal confined in a capillary tube. The phenomenon is explained by a pure thermal nonlinear effect due to dye absorption.
-
(1999-03-01)We present the design, fabrication, and test of a polarizing beam splitter grating for operation at 633 nm under a angle of incidence. This component is compact and its fabrication is reproducible enough to be integrated ...
-
(1999-12-01)The ideas behind much of the current research in optics have been known for a long time and many are even found in Nature. However, constant advances in technology often make possible that which was previously considered ...
