摘要:
This assembly of an object and a support is achieved by using solder bumps. At least two wettability areas are made respectively on object and on support. Each solder bump ensures electrical contact and mechanical fixing firstly to one of the wettability areas of object and secondly to one of the wettability areas of support. The melting temperature of solder bumps is lower than the melting temperature of each of the wettability areas. Each wettability area of object forms an angle of 70° to 110° with respect to each wettability area of support. Object and support are mutually distant.
摘要:
An optical duplexer intended to receive light at a first optical wavelength and to transmit back light at a second optical wavelength, including, on a substrate, successive layers forming a photoreceptor of the first optical wavelength, a selective filter letting through the first optical wavelength, and a waveguide having a surface including a grating which is transparent for the first optical wavelength and diffracting for the second optical wavelength.
摘要:
A method for aligning an optical fiber and a submicronic waveguide of an integrated optical circuit, the waveguide including a core surrounded with upper and lower layers forming an optical cladding, including the steps of: (a) forming, in the upper layer, one or several openings capable of extracting light from the waveguide; (b) roughly positioning the optical fiber to send light into the waveguide; (c) finely moving the optical fiber with respect to the waveguide and detecting the position causing the extraction of a maximum amount of light at the level of the opening(s); and (d) depositing a glue binding the optical fiber to the optical circuit and filling the opening(s).
摘要:
An optical device including at least one first optical waveguide coupled to a second optical waveguide of smaller cross-section which penetrates into it on the side of a first end. The first optical waveguide is capable of being coupled with an optical fiber on the side of a second end. A surface of the first optical waveguide includes a diffraction grating capable of introducing-extracting-sending back light into and from the first optical waveguide.
摘要:
This relates to an opto-electronic device comprising at least two opto-electronic components (1, 2) which work together, including a first one that is a surface light emitting laser (1) and another opto-electronic component (2). Each of the opto-electronic components (1, 2) is mounted on a main face (3.1, 3.2) that is different and opposite an intermediate layer (3) incorporating a grating coupler (5) coupled to an optical wave guide (4) designed to transport part of the light emitted by the surface emitting laser (1). The grating coupler (5) is sandwiched between the emissive face of the surface emitting laser (1) and the other opto-electronic component (2).
摘要:
The disclosure relates to an optical device comprising an assembly and optical coupling cover between at least one waveguide integrated onto a first support and at least one optical fibre integrated onto a fibre connector, wherein the cover is capable of being fixed to the first support and comprises: one or several grooves designed to allow to the cover to nest with the connection pins of the optical fibre connector, at least one other groove equipped with longitudinal sides, a base, and a wall forming an angle that is not nil with the base and the sides, wherein said other groove is designed to be positioned in the extension of the optical axis of the fibre and so that said wall is located opposite the fibre, an optical system positioned at the level of a wall of said other groove, capable of deviating towards the fibre a luminous beam from the wave guide and/or deviating towards the wave guide a luminous beam from the optical fibre.
