Process of increasing structure integration density in microelectronics contributes to even more restricted tolerances of electronic packaging. For this reason advanced packages must be measured with very high accuracy. In previous research a white light interferometer with reference light beam was built. This paper is sacrificed to the influences on measurement accuracy done with white light interferometer with a reference light beam. In the first part of the paper all possible influences on measurement accuracy will be named. Then the most significant measuring errors for Michelson interferometer with reference light beam will be widely introduced and estimated

For one and a half decades world-wide to it one researches how optical waveguides can be implemented inside of conventional printed wiring boards. These make themselves particularly necessary for high bandwidths. Selected points of the packaging of electrical-optical boards are located in the centre of this contribution. Among other things, the paper contains the approach to integrate the optical layer and to place the light-emitting and detecting devices

We outline a method of calculating the spectral response of a contra-directional grating-assisted optical coupler. Interference of reflected / transmitted supermodes is taken into account. Sample numerical results for a planar device are presented. The results include spectral response of a sole grating-assisted coupler, changes introduced by an additional coupler without grating and changes introduced by refractive-index modulation induced by an additional control beam

Photonic crystals, that have an influence on wave propagation, are in a point of interest for several years. Despite of the fact that they have some similarities to semiconductors, modelling methods cannot be directly transferred since magnetic and electric fields are treated like vectors not scalars as it is in case of wave function in Schroedinger's equation. There were created methods that can be divided into two groups. The first one is connected to calculation of dispersion properties of the photonic crystal, while the second one gives possibility to analyse wave propagation through photonic crystal. This paper shows the most commonly used methods of modelling photonic crystals: among other PWM, FDTD

The integration of optical interconnections on a printed circuit board (PCB) is challenging, as it should remain compatible with existing PCB manufacturing technology. This integration level requires compatibility with the established manufacturing and assembly processes of the conventional electrical board technology, which is based on laminated FR4-substrates and making use of well-known placement and assembly techniques. Since printed circuit boards will continue to be the most important components of electronic equipment, still the most critical problem of the integration of optical interconnections in PCB is coupling the light in and out of the optical plate. By reason of that, various principles and interconnection architectures for optical beam routing were investigated.

Signal propagation within multimode waveguides with rectangular cross sections is modeled by an approximative determination of the propagating modes. Precondition for the approach is a small difference between the refractive indices of the waveguide's core and cladding leading to a small numerical aperture. The approximation yields good results for modes far away from cutoff. As the roughness between core and cladding of real board-integrated waveguides results in a stronger attenuation of the higher order modes compared to the modes of lower order, the approximation seems to be well suited for modeling this kind of waveguides

This paper shows a new method for fiber-chip coupling. To optimize coupling between a light emitting device and a polymeric fiber, special modules were developed. In this paper the measurement results of these modules are presented. Among other things, the PI-curve and the median field were measured and long-term tests were run
