    摘要: A coupling structure for coupling optical radiation, i.e., light, between an optical fibre and an optical device, e.g., a laser diode or a photodiode. The coupling structure has an optical through-via which guides the optical radiation to or from the optical fibre. Light exiting the fibre travels through a guidance channel so it remains substantially confined to a narrow optical path that mimics the fibre core. Conversely, light enters the fibre after having traveled through the guidance channel. The guidance channel has a first core region, the “channel core”, having first refractive index surrounded by a second region, the “channel cladding” having a second refractive index smaller than the first refractive index. The coupling structure, including the guidance channel, is preferably made of semiconductor-based material, more preferably of silicon-based material. The guidance channel is preferably silicon oxide. The coupling structure further has a fibre drive-in element, which facilitates insertion and alignment of the optical fibre to the guidance channel.

    摘要: A method for bidirectional optical communication comprising the steps of:—at a first optical line terminal, directly modulating a laser source to generate a downstream optical signal which has an optical power spectrum comprising two peaks having a frequency separation and a non zero power difference at generation;—propagating said downstream optical signal at a distance along an optical line comprising at least a first optical fiber propagating said downstream optical signal to a second optical line terminal;—at the second optical line terminal: power splitting said downstream optical signal to generate a first and a second power portion of said downstream optical signal, spatially separated; passive filtering said first power portion of said downstream optical signal so as to increase in absolute value a respective power difference of said two peaks, so as to obtain a filtered optical signal which is thereafter detected; and amplitude modulating the second power portion of the downstream optical signal so as to obtain an upstream optical signal having a second amplitude modulation;—propagating back along said optical line the upstream optical signal to the first optical line terminal;—at said first optical line terminal, detecting said upstream optical signal; wherein the method further comprises the step of passive filtering said downstream optical signal and/or said second power portion of the downstream optical signal and/or said upstream optical signal, so as to lower, in absolute value, a respective non zero power difference of said two peaks.

    摘要: A process for manufacturing an integrated device includes the steps of: providing a silicon substrate on which a silicon dioxide structure is arranged and forming a trench having first and second essentially vertical walls relative to the substrate in the structure by means of anisotropic-type etching. A concavity having a sloped wall relative to the substrate is formed by isotropic-type etching which removes the second wall so that the concavity is open to the trench and the sloped wall faces the first wall.
