Descrizione del progetto
Photonic components
The proposed project will realise compact, high-performance, CMOS-compatible and cost-effective planar optical amplifiers and lasers for next generation optical networks. The drive to combine the functionality of silicon electronics with optical data transmission to yield silicon opto-electronic integrated circuits operating at 1.5 ¿m is currently a technological priority of both the communication and the microelectronics communities. The present proposal intends to exploit the quantum properties of Si nanoclusters (Si-ncs) to efficiently excite erbium ions, which are the optically active species responsible for light amplification. In this way, the project will overcome the principal problems that have precluded the development of such amplifiers to date: poor emission efficiencies of erbium in silicon, small excitation cross-sections for erbium in silica, the requirement for expensive pump sources. The project will exploit two approaches: hybrid and monolithic integration. The hybrid approach will involve, for example, flip-chip bonding of an ion-exchanged glass waveguide with a planar Er/Si-nc codoped layer. Monolithic silicon amplifiers will be fabricated by co-doping silicon waveguides with Si-ncs and erbium ions. The devices will be electrically and/or optically pumped, the latter using a low-cost LED. Planar packaged devices with gains of 10dB less than 5cm in length are envisaged, allowing the deployment of inexpensive photonic components for metropolitan networks and fibre-to-the-home.The consortium includes universities, research centres active in electronics, signal processing and advanced optics, and a well-established SME in the field of optical subsystems.
