“…Overall, it is clear that for photonics-based mm-wave technologies, there is a shift from fiber-based systems towards PICs, as the latter enable more complex and reliable functionality in a much smaller footprint and at a lower cost, while optimizing the energy consumption. Combined with the fact that optical fibers are finding their way into more and more short-haul links due to the increasing bandwidth requirements [393,394], these PIC-based mm-wave components will play a key role in telecommunication networks and increasingly obsolete the all-electronic chips. The same applies to sensing and imaging applications, where electromagnetic waves in the mm-wave and THz bands enable more sensitive detection than in other frequency bands.…”

Technological innovation with millimeter waves (mm waves), signals having carrier frequencies between 30 and 300 GHz, has become an increasingly important research field. While it is challenging to generate and distribute these high frequency signals using all-electronic means, photonic techniques that transfer the signals to the optical domain for processing can alleviate several of the issues that plague electronic components. By realizing optical signal processing in a photonic integrated circuit (PIC), one can considerably improve the performance, footprint, cost, weight, and energy efficiency of photonics-based mm-wave technologies. In this article, we detail the applications that rely on mm-wave generation and review the requirements for photonics-based technologies to achieve this functionality. We give an overview of the different PIC platforms, with a particular focus on hybrid silicon photonics, and detail how the performance of two key components in the generation of mm waves, photodetectors and modulators, can be optimized in these platforms. Finally, we discuss the potential of hybrid silicon photonics for extending mm-wave generation towards the THz domain and provide an outlook on whether these mm-wave applications will be a new milestone in the evolution of hybrid silicon photonics.

“…In particular, excitation of higher-order modes can be enhanced by launching a beam with a transverse offset from the center axis [7,32,33,54] or with an angular offset [54]. Plastic optical fibers having core diameters of 0.5-1 mm [55,56] are used in short-range links. In these plastic fibers, index inhomogeneity causes strong mode coupling, which significantly reduces the GD spread and increases the supportable bit rate [16,57,58].…”

“…In these plastic fibers, index inhomogeneity causes strong mode coupling, which significantly reduces the GD spread and increases the supportable bit rate [16,57,58]. However, high losses in plastic optical fibers (33 dB/km is the minimum value given in [56]) limit link distances to under 100 m [56].…”

The integration of plasmonic nanostructures in an optrode sensing system holds significant promise for online and remote detection via surface-enhanced Raman scattering (SERS) method. This study focuses on the impact of the shape and composition of plasmonic materials on their ability to enhance surface-enhanced Raman scattering (SERS) signals. We compared the SERS performance of optical fiber (OF)-based sensors (OFSs) with flattened end faces, which were decorated with six mono-and bimetallic nanomaterials: Au nanoparticles (NPs), Ag NPs, Agcoated Au NPs (Au@Ag CSNPs), Au nanostars (NSs), Ag NSs, and Ag-coated Au NSs (Au@Ag CSNSs). Among these nanomaterials, polyhedral Au@Ag CSNSs demonstrated superior SERS enhancement, mainly attributed to multifaceted hotspots on their surface and the plasmonic coupling between the Au core and Ag shell. This allowed for precise customization of the surface plasmon resonance (SPR) and distinct enhancement of the SERS efficiency by modulating the thickness of Ag shell. Our sensing system exhibited great potential, achieving the lowest detection limit of ∼5 × 10 −8 M for crystal violet, which surpasses the performance of previous OF-based sensors with the same type of flattened facets.
