摘要： Transmitter module for optical interconnections, comprising a metal container housing an optical emitting device, an integrated circuit containing the driving circuit of the emitting device and an optical fibre extending outside the container, the emitting device being mounted on a metallic ground area realized on the integrated circuit. The cathode is electrically connected to the ground area and the anode is connected to a second metal area, connected with the output of the driving circuit. The module uses a type of assembly which minimises problems due to the length of the connecting wires, to parasitic effects and to the effects of signal reflections due to impedance mismatching. It also requires reduced power for its operation and it is provided with a structure facilitating dissipation.

摘要： In the fiber and in any fiber (F), a reflecting surface (F1) is created that is generically tilted with respect to the main propagation path (T1) of the optical radiation in said fiber, so as to originate by reflection an additional propagation path (T2) that is generically deflected with respect to said main propagation path (T1). In a mounting support (2) common to the fiber (F) and the related opto-electronic component (O), a groove is made along an external face (2a) so as to accomodate the optical fiber (F) in a tight condition. The groove (3) is then covered through a laminar cover, that is transparent to the radiation and has a flat surface (4a). The fiber (F) is inserted into said groove in order that said deflected propagation path (T2) passes through said cover (4) of material transparent to the radiation, and the opto-electronic component (O) is mounted on said cover (4) in alignment with said deflected propagation path (T2).

摘要： A device for monitoring the emission wavelength of a laser includes a semiconductor slice or slab having first and second opposed surfaces. The semiconductor slice is exposed to the radiation at an angle such that a portion of said radiation impinges onto the first surface at angles in the vicinity of the Brewster angle for the first surface. The radiation is thus refracted into the semiconductor slice and caused to propagate towards the second surface of the semiconductor slice. A wavelength selective filter is arranged at said second surface having associated a photodetector to generate a signal indicative of the wavelength of the radiation.

摘要： An optical wavelength control system for an optical source includes a beamsplitter arrangement for propagating radiation from the source over two paths. First and second photodetectors are arranged each in a respective one of said two propagation paths, while a wavelength selective optical filter is interposed in the propagation path from the source to the first photodetector. The first and second photodetectors generate photocurrents indicative of the possible displacement of the actual wavelength of the radiation from said source with respect to a reference wavelength and the power emitted by the optical source, respectively. The system includes a support bench extending in a given plane and the beamsplitter arrangement is arranged to split the radiation from said source towards the photodetectors in a direction substantially perpendicular to the given plane of the support bench.
