Title: Optical waveguide having negative dispersion and large aeff
Inventor: MITCHELL BRIAN E
IPC: G02B6/036
Filed: 2000-06-20
Abstract: The invention is directed to a single mode optical waveguide fiber profile (18, 20, 22, 24) that provides relatively large effective area while limiting macrobend loss. The large effective area results from configuring the core of the waveguide fiber to shift propagated light power away from the waveguide center. Macrobend loss, as measured by pin array or 20 mm mandrel testing, is maintained low by means of a power-limiting index depression (24) surrounding the central core region of the waveguide. In addition, low attenuation is achieved and cut off wavelength is controlled to provide a telecommunications operating window in the wavelength range of about 1250 nm to 1700 nm.

Abstract: L'invention porte sur un procédé de simulation d'un système physique utilisant des techniques des éléments finis. Selon ce procédé, on résout deux ou plusieurs modèles distincts correspondant à des régions distinctes dans le système modélisé, chacune ayant un évaluateur correspondant. Les noeuds qui se lient sur les limites entre les modèles peuvent avoir différentes valeurs correspondant aux différents modèles. Lorsqu'un modèle particulier est résolu, l'évaluateur de ce modèle est utilisé pour obtenir les valeurs appropriées de chacun de ces noeuds communs. Selon une réalisation, un premier modèle est défini, puis une région correspondant à une caractéristique particulière du système est détachée de celle-ci. Un modèle d'éléments finis correspondant à la caractéristique est ensuite inséré dans la région. Les éléments finis peuvent être adaptés pour partager des noeuds entre leurs limites.

Inventor: IM JAMES S
IPC: H01L21/02
Filed: 2001-10-09
Abstract: L'invention concerne un procédé et un appareil destinés au traitement d'une couche métallique mince située sur un substrat, permettant de contrôler la dimension du grain, la forme du grain, l'emplacement et l'orientation du joint de grain dans la couche métallique. Ce procédé consiste à soumettre la couche métallique à une impulsion laser excimère ayant un diagramme d'intensité défini par un masque permettant d'obtenir des zones d'ombre et des micro-faisceaux. Les régions de la couche métallique couvertes par un micro-faisceau fondent sur toute leur épaisseur, et les régions de la couche métallique couvertes par une zone d'ombre restent au moins partiellement intactes. Les régions au moins partiellement intactes sont contiguë à des régions fondues adjacentes. Après application de l'impulsion laser excimère, les régions fondues de la couche métallique se resolidifient. Au cours de la resolidification, les régions au moins partiellement intactes amorcent la croissance des grains dans les régions fondues adjacentes pour produire des grains plus grands. Après resolidification des régions fondues, suite à l'application de l'impulsion laser excimère, la couche métallique est soumise à une seconde impulsion laser excimère ayant un diagramme d'intensité décalé, de façon que les régions d'ombre couvrent les régions de la couche métallique comprenant moins de grains, de plus grande dimension. Les régions de la couche métallique couvertes par un des micro-faisceaux décalés fondent sur toute leur épaisseur, alors que les régions de la couche métallique couvertes par une des régions d'ombre décalées restent au moins partiellement intactes. Lors de la resolidification des régions fondues, suite à l'application de la seconde impulsion laser, les grains plus grands situés dans les régions au moins partiellement intactes non fondues amorcent la croissance de grains encore plus grands dans des régions fondues adjacentes. Les étapes d'application d'un premier rayonnement, de resolidification, et d'application d'un second rayonnement sur la couche métallique, peuvent être répétées en fonction des besoins, jusqu'à ce que la structure des grains désirée soit obtenue dans la couche métallique.
