    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: An optoelectronic module includes a first sub-module and a second sub-module. The first sub-module has a surface with a cavity formed therein, and includes an integrated waveguide provided with a first optical port accessible from the cavity. The second sub-module faces the first sub-module. A metallic wall extends from the first sub-module to the second sub-module, and surrounds the cavity to define a hermetically closed chamber. An optoelectronic device is coupled to at least one of the first and second sub-modules, and is included in the chamber. The optoelectronic may comprise a second optical port coupled to the first optical port in the first sub-module.
