CA 2449106

An anisotropically etched prism assembly including a device portion (5904), a light coupling portion (5110) and an alignment portion (5106). The anisotropically etched prism assembly having a plurality of optical devices arranged in a first fixed pattern. Each pair of said plurality of optical devices spaced a first prescribed distance apart. The light coupling portion (5110) including a plurality of anisotropically etched prisms arranged in a second fixed pattern so as to correspond with a respective one of the plurality of optical devices. Each one of the pairs of said plurality of anisotropically etched prisms are spaced a second prescribed distance apart, the second prescribed distance substantially equals the first prescribed distance. The alignment portion (5106) aligns the light coupling portion and the device portion.

Un ensemble de prismes à gravure anisotropique comprend une partie dispositif (5904), une partie de couplage optique (5110) et une partie d'alignement (5106). L'ensemble de prismes à gravure anisotropique comprend des dispositifs optiques aménagés selon une première configuration fixe. Chaque paire desdits dispositifs optiques est séparée par un premier espace prescrit. La partie de couplage optique (5110) comprend plusieurs prismes à gravure anisotropique aménagés selon une deuxième configuration fixe de manière à correspondre au dispositif optique correspondant. Chacune des paires de ces prismes à gravures anisotropique est séparée par une deuxième distance prescrite, sensiblement égale à la première. La partie d'alignement (5106) aligne la partie de couplage optique et la partie dispositif.
