(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)Helicoidal bianisotropic mediums (HBMs) are periodically nonhomogeneous and possess structural chirality. We establish a variety of conditions concerning the equivalence of planewave propagation along the spirality axis ...
-
(1999-03-01)An alignment-free optical module based on a 2-f optical system with optical microconnectors is proposed for free-space optical interconnection. The alignment accuracy is evaluated theoretically from paraxial optics. The ...
-
(1999-07-01)In this paper, a scheme using anisotropic diffraction to implement the 2 × 2 switching element in a one-block Fe:LiNbO3 photorefractive crystal is suggested. To decrease the crosstalk among the four individual photorefractive ...
-
(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. ...
-
(2000-03-01)This paper reports the imaging laboratory tests on a fibre-linked telescope array including three interferometric arms. We demonstrate the necessity of using polarization-maintaining fibres to obtain a steady calibration ...
-
(2000-11-01)Simplified analytic expressions are derived for the optical propagation matrix of magnetic anisotropic Kerr media using the Lagrange-Sylvester interpolation polynomial. This expression is used to investigate magnetic Kerr ...
-
(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 ...
-
(1999-07-01)Despite the rapid growth of near-field optical microscopy in the past decade, many questions about the imaging properties of near-field microscopes remain unanswered. In this paper we describe a novel near-field optical ...
-
(2000-05-01)In this letter we report on an initial investigation into the printing of diffracting objects via the high-speed, low-cost, printing process of offset-lithography, a method more commonly used in the printing of books and ...
-
(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 ...
