“…Moreover, for the reciprocity of the antenna behavior, it can also act as a receiver transforming the wireless signal into a guided one. Further details on the radiation properties of the taper antenna are reported in [10,20]. It is worth underlining that, as discussed in [10,20], the radiation gain can be improved up to about 20 dB by adding dielectric directors to the taper antenna.…”

“…Further details on the radiation properties of the taper antenna are reported in [10,20]. It is worth underlining that, as discussed in [10,20], the radiation gain can be improved up to about 20 dB by adding dielectric directors to the taper antenna. However, since the focus of this work is the analysis of the propagation channel in presence of obstacles, we will consider only simple taper antennas, which exhibit a sufficiently high gain and are easier to fabricate.…”

“…An important requirement for optical antennas for OWiNoCs is a high gain in the longitudinal direction (onchip plane). On this frame, two types of antennas have been developed in recent years, the plasmonic and the dielectric ones [10][11][12][13][18][19][20], both with their specific traits [20]. Dielectric antennas [10,20] allow to reach very high gain in the longitudinal direction, between 16-23 dB.…”

“…In previous studies, structures with increasing geometrical complexity have been addressed by considering, initially, simple boundless homogeneous media [10][11][12][13][18][19][20][21][22][23]. Then, more realistic structures based on a homogeneous cladding, with air on top and Silicon layer on bottom, have been considered using both RT and FDTD [21][22][23][24].…”

Networks-on-chip are being regarded as a promising solution to meet the on-going requirement for higher and higher computation capacity. In view of future kilo-cores architectures, electrical wired connections are likely to become inefficient and alternative technologies are being widely investigated. Wireless communications on chip may be therefore leveraged to overcome the bottleneck of physical interconnections. This work deals with wireless networks-on-chip at optical frequencies, which can simplify the network layout and reduce the communication latency, easing the antenna on-chip integration process at the same time. On the other end, optical wireless communication on-chip can be limited by the heavy propagation losses and the possible cross-link interference. Assessment of the optical wireless network in terms of bit error probability and maximum communication range is here investigated through a multi-level approach. Manifold aspects, concurring to the final system performance, are simultaneously taken into account, like the antenna radiation properties, the data-rate of the core-to core communication, the geometrical and electromagnetic layout of the chip and the noise and interference level. Simulations results suggest that communication up to some hundreds of μm can be pursued provided that the antenna design and/or the target data-rate are carefully tailored to the actual layout of the chip.

Optical properties and far field radiation of periodic nanostructures fed by an optical waveguide for applications in fluorescence and Raman scattering

Various systems based on nanostructures built on optical waveguides have recently appeared in literature, since this configuration guarantees an efficient optical feeding to nano-elements and/or the possibility to manipulate guided signals. In this work, we present the analysis of the optical scattering properties of such type of structures, more specifically a periodic array of Au nano-cylinders or nano-domes fabricated upon an ion-exchanged waveguide, an integrated system considered for fluoroscopy and Raman spectroscopy. Absorption, scattering and extinction were calculated by means of Finite Difference Time Domain (FDTD) simulations and Scattering Theory. We took advantage of some particular adaptations to apply the classical scattering theory to this context, and used it to extract the far-field radiation pattern. We show that the rectangular periodicity allows to obtain highly collimated beams and negligible irradiation in a wide angle range, which enables the possibility to steer away the undesirable excitation signals from the detectors, avoiding a mixing with emitted photons from molecules. Our analysis suggests that, in the context of this setup and applications, the modeling of the nanostructures, which aims at the tuning of the plasmonic enhancement of the emission, can be relatively separated from the definition of spatial filtering through the periodic array. Our results add new considerations to the list of potentialities of this configuration for the development of efficient integrated surface enhanced spectroscopic setups.
