Description

In the last years, optical on-chip data transmission has been proposed as a key technology to overcome the bandwidth and energy limitations of electrical interconnects in networks-on-chip for high-density multi-core architectures. Solutions based on Silicon Photonics (SiP) using waveguides for long interconnects and ring-resonator-based switching fabrics have been extensively investigated. Optical-Networks-on-Chip (ONoCs) have the benefit of large bandwidths, low propagation losses and compatibility with electronics. However, this approach can suffer from problems related to complex layout, crosstalk, sophisticated routing technologies and high-power consumption. Optical Wireless Networks (OWNoCs) are a possible alternative that, by combining optical waveguide-based interconnections with optical wireless links, aims at overcoming these issues. Recent results obtained on OWNoCs will be summarized. Optical antenna design, channel modeling and optimization, fabrication and measurement steps will be illustrated and discussed. Moreover, an Optical Wireless Interconnection Block allowing wireless reconfigurable interconnections among different transmitters and receivers will be shown.
