Modernising Telecommunications

New mechanisms for optical communications based on integrated optics and optical fibres for multiplexing using wavelength division, optical routing, integration/derivation multiplexers and wireless optical connections, in the fields of optical fibre sources and vision.

At the Centre for Applied Photonics (CAP) we conduct R&D projects aiming to develop new devices for optical communications. We have created innovative mechanisms based on integrated optics and optical fibres for multiplexing using wavelength division, optical routing, integration/derivation multiplexers and wireless optical connections, in the fields of optical fibre sources and vision.

We are recognised for fabricating optical fibre or integrated optics filters, which are exposed to intense radiation patterns emitted by ultraviolet lasers. These submicrometric patterns cause periodic changes to the refractive index (Bragg gratings), which makes it possible to manufacture filters with a broad spectral selectivity.

The equipment developed at CAP and installed in the laboratories are assets for producing not only uniform, apodised and chirped gratings with phase jumps, but also long period gratings.
