Patent CA-2336941-A1 (CA)
Inventor: SASAOKA EISUKE
IPC: G02B6/036
Filed: 1999-07-07
Abstract: Cette invention se rapporte à une fibre optique comprenant au moins une structure destinée à supprimer efficacement l'augmentation de la perte par microcourbure, notamment de préférence sur des fibres optiques à dispersion aplatie et des fibres optiques à dispersion compensée, et servant à compenser la caractéristique unimodale de la bande de longueur d'onde utilisée. Plus particulièrement, cette fibre optique possède un diamètre égal ou supérieur à 140 µm et par conséquent une rigidité élevée. Etant donné que l'augmentation de la perte par microcourbure est supprimée efficacement et que le diamètre de la fibre est inférieure à 200 µm, la probabilité de rupture due à une contrainte de courbure n'entraîne pratiquement aucun risque. Cette fibre optique présente un diamètre de champ de mode plus grand, de telle sorte que la densité d'énergie optique par unité de section transversale est faible et les phénomènes optiques non linéaires sont supprimés efficacement.

Abstract: It has been now surprisingly discovered after extensive research that 2-halo - 4,6-bisaryl-1,3,5-triazine can be prepared with unprecedented selectivity, efficiency, mild conditions, and in high yield by the reaction of cyanuric halide with aromatics in the presence of at least one Lewis acid and at leas t one reaction promoter. This reaction is also unprecedently general as a variety of aromatics can be used to produce a wide selection of 2-halo-4,6- bisaryl-1,3,5-triazines. The novel approach includes the use of the reaction  promoters in combination with at least one Lewis acid under certain reaction  conditions to promote the formation of 2-halo-4,6-bisaryl-1,3,5-triazine compounds from cyanuric halide. Preferably, the Lewis acids and reaction promoters are combined to form a complex. 2-halo-4,6-bisaryl-1,3,5-triazines  are key intermediates for making 2-(2-oxyaryl)-4,6-bisarly-1,3,5-triazine class of UV absorbers.

Patent CA-2359506-A1 (CA)
Inventor: KOESTER DAVID ALLAN
IPC: G02B6/13
Filed: 2001-10-22
Abstract: A microelectronic reflector is fabricated by forming a first polysilicon layer on a microelectronic substrate, forming a first phosphosilicate glass (PSG) layer on the first polysilicon layer, and reactive ion etching to remove the first PSG layer from at least a portion of the first polysilicon layer. A second polysilicon layer is formed on at least a portion of the first polysilicon layer from which the first PSG layer was removed and a second PSG layer is formed on at least a second portion of the second polysilicon layer. Reactive ion etching is performed to remove the second PSG layer from at least a portion of the second polysilicon layer. A third PSG layer then is formed on at least a portion of the second polysilicon layer from which the second PSG layer was removed.  Reactive ion etching is performed to remove the third PSG layer from at least a portion of the second polysilicon layer. By forming a third PSG layer, and reactive ion etching this layer, additional stress may be created in the first and/or second doped polysilicon layers that bends the ends of the doped first and/or second polysilicon layers towards the microelectronic substrate upon release of the treated polysilicon layer from the substrate, compared to doped polysilicon layers on which the third PSG layer was not formed and reactive ion etched. This increased stress may be counteracted by forming a stress-correcting layer on at least a portion of the second polysilicon layer from which the third PSG layer was removed, and then forming a reflective layer such as gold on at least a portion of the stress-correcting layer. The stress-correcting layer preferably comprises platinum, which can produce high stresses that can counteract the stresses in the first and second doped polysilicon layers, to thereby allow a flat mirror and/or beam to be produced.
