Dating from the fifth century bce, two Phoenician anthropoid sarcophagi, a male and a female, found in Gadir (Cadiz, Spain), are so far the most ancient marble sculptures found in the Iberian Peninsula. The identification of the source of the marble used to produce them has been a subject of controversy for several decades and has recently resurfaced when it was published that they were made by Phoenician...
The concept and experimental results to manufacture electrical-optical circuit boards (EOCB) with buried optical waveguides using thin-glass sheets (display glass) are presented. An ion-exchange process was developed to manufacture the graded index waveguides in thin-glass sheets. Besides of their excellent optical properties no mechanical structuring is necessary for the waveguides. Their properties...
The implementation of waveguides in thin glass foils results in graded index multimode waveguides. The paper presents two numerical approaches for modeling signal propagation within such waveguides.
Optical interconnects integrated into electrical printed circuit boards have to be low cost and their manufacturing process has to comply with the established printed circuit board technology. Nearly all step index waveguides developed under these premises show rough surfaces between core and cladding leading to completely different power-loss characteristics of the propagating modes. In this paper...
Accurate modelling of signal propagation on optical interconnects is very important to improve and speed up the progress of integrating optical interconnections into the conventional manufacturing process of electrical-optical layouts. In this paper a model is introduced which represents the coupling of optical power from a laser diode into a dielectric waveguide with a rectangular cross section....
