Abstract: A module for converting light energy into electric energy (MC1) for use in an optical network to convert into electric energy light energy derived from an optical signal transported in an optical fiber (FTa1) from a light energy source (OS1). The module can be used in remote powering and/or remote control devices for optical networks.

Abstract: This device or junction is essentially constituted by a substrate made from an electrically insulating material (2), a vertical wall (4) formed on the substrate and extending in a given direction (x), said wall being made from said insulating material, a superconducting material ribbon (8) in two separate parts (10, 12) located on either side of the wall and bearing on the latter, the ribbon being oriented in a direction perpendicular to the said direction, and two interconnection contacts (14, 16) respectively placed on the two portions of the ribbon.

Abstract: A superconducting screen printing ink comprises an organic composition, a mineral binder and a mineral composition which is a high temperature superconducting Bi-Sr-Ca-Cu-O material or a precursor therefore. A thick superconducting film is produced by screen printing deposition of the ink on a substrate through a mask, drying and then baking the deposited ink. The ink and film are useful in microelectronics.
