    摘要: A common InP semiconductor substrate device includes a laser emitter H1 for emitting waves having a first wavelength such as 1,300 nm, a photodiode H2 for receiving and detecting waves having a second wavelength such as 1,550 nm, and a separator G absorbing the waves having the first wavelength, the separator being interposed between the laser emitter H1 and the photodiode G for protecting the photodiode against the waves having the first wavelength. An absorption measurement mechanism Q delivers a signal iG representative of the power of the waves absorbed by the separator G, to make it possible to regulate operation of the laser emitter H1. The semiconductor substrate device is particularly applicable to implementing end devices to be installed on subscriber premises for subscribers to optical fiber interactive local area networks.

    摘要: An automobile automatic transmission control device consists of a sector fixed to a vehicle. A control lever is pivoted to the sector about a fixed axis. A plurality of lockout notches are formed on an edge of the sector along a locus centered on said fixed axis. A plurality of self-locking notches are formed in said sector about a locus centered on said fixed axis. The control lever is provided with a rod biased into engagement with the lockout notches so as to prevent the unintentional pivoting of the lever. The control lever is also provided with a plurality of self-locking elements which cooperate with the self-locking notches to establish transmission selection positions. The rod can be moved out of engagement with the lockout notches by engagement of a trigger release mounted on one end of the lever.

    摘要: An integrated opto-electronic component includes an amplifying segment coupled to a tuning segment to provide a wavelength tunable laser oscillator function insensitive to the polarization of optical waves that it receives. The amplifying segment is designed to be insensitive to polarization. The tuning segment includes a Bragg grating and a waveguide dimensioned to procure transversely monomode laser emission with rectilinear polarization. Applications include wavelength converters and stabilized gain amplifiers, in particular for optical transmission.

    摘要: The wavelength tunable optical filter (1) comprises a resonant cavity (4) delimited by two opposite reflective elements (8, 8′) which are not wavelength selective, and a reflector (7) external to the cavity (4). The external reflector (7) exhibits transmission peaks for an integer number N of optical frequencies and the Fabry-Perot cavity (4) delimiting a phase tuning section (11) is sized so that the distance between the optical frequencies of any two resonant modes of the cavity (4) is never equal to the difference between the optical frequencies of any two transmission peaks of the external reflector (7).

    摘要: In a method of fabricating a surface-emitting laser, to assure good electrical confinement and good flatness of the mirrors defining the resonant cavity of the laser an electrical confinement layer is formed by carrying out the following steps: forming an undercut layer, at least one growth step on the undercut layer, forming a mesa defining the shape and the location of the top mirror and exposing the undercut layer on its vertical walls, and controlled lateral etching of the undercut layer. Applications include the fabrication of a semiconductor laser on a III-V (e.g. InP or GaAs) substrate.
