摘要： An optical device integrated on a planar substrate is disclosed, comprising a Y-branch attenuator optically coupled to a Mach-Zehnder modulator. The device also comprises means for reducing a crosstalk caused by unguided radiation between the Y-branch attenuator and the Mach-Zehnder modulator. In one embodiment, the reduction of the crosstalk is obtained by connecting the Mach-Zehnder modulator to one arm of the Y-branch attenuator. The invention also comprises a transmitting module including the integrated device.

摘要： A method of making an all-fiber Mach-Zehnder interferometer comprising at least two optical fibers (201,202) comprises the steps of bringing the fibers in a reciprocal contact relationship for a contact section thereof; fusing together and tapering the fibers in at least a first portion (291,292) of said contact section; forming at least two optical couplers (5,6) between the fibers in a second and a third portions of said contact section, located at opposite sides of said first portion. The fusing and tapering at said first portion causes said fibers to be physically joined but does not result in significant optical coupling between the two fibers.

摘要： An optical switch comprises at least a first input optical guide (1) having a first beam exit termination (11) and a first and second output optical guides (3,4) respectively having first and second beam entrance terminations (31,41), and a movable reflecting element (6), operatively associated with said exit termination and entrance terminations, movable between a first position and a second position, the first position causing an optical beam (14) exiting from said exit termination to be directed towards the first entrance termination, the second position causing said optical beam to be directed towards the second entrance termination. A normal direction to each of said exit termination and entrance terminations forms a first angle (α1), different from 0°, with an optical axis (12,32,42) of the respective guide, said first angle depending on optical properties of the guides and of an optical transmissive medium between the exit termination and entrance terminations and being such that back-reflected beams inside the guides are attenuated with respect to a guide termination perpendicular to the optical axes of the guides. The optical switch is suitable to be integrated in a substrate, with integrated guides converging to a recess formed in the substrate and adapted to movably house the reflecting element.

摘要： A method for writing a Bragg grating in a waveguide comprises the steps of placing the waveguide in a writing position in which the waveguide extends essentially along one axis; generating a beam of ultraviolet radiation; executing a first and a second scan with the said beam along the waveguide through a phase mask, in such a way as to generate interference fringes capable of modifying the refractive index along the said waveguide in a predetermined way; moving the phase mask, during the first or the second scan, with an oscillatory motion about one of its equilibrium positions and along a direction lying at an angle of less than 90° to the axis of the said waveguide, in such a way as to produce, in this scan, an essentially zero envelope of the refractive index; and varying the intensity of the energy of the ultraviolet radiation in a controlled way along the waveguide during the first and the second scan, for example by controlling the scanning velocity.
