Special Issue Information

Dear Colleagues,

The recent technological advances in the field of dielectric photonics, integrated optics, and optical fiber-based systems have paved the way for novel application areas based on the employment of optical beams. Photonics, integrated optics, and optical fiber-based systems constitute nowadays a feasible technological platform, successfully exploited in 5G networks, Internet of Things (IoT), Industry 4.0, Telemedicine, Environment Monitoring, Precision Agriculture. In this context, innovative hybrid solutions, integrating optics with antennas and systems based on  micro- and millimetre wave propagation are strongly spreading.

Optical beam propagation/processing allows application in biomedicine, via the interaction of light with biological tissues, such as in optical diagnostic and therapy; communication by exploiting, in addition to the conventional fiber optic systems, microwave photonics and radio-over-fiber techniques; material processing, via high brilliance and high power optical sources; sensing with the development of novel LiDAR (Light Detection and Ranging o Laser Imaging Detection and Ranging) systems, novel SERS (Surface Enhanced Raman Spectroscopy) substrates, microstructured optical fiber and photonic crystal based sensors; aerospace application via the developing of high performance devices including optical gyroscopes, medium infrared Mid-IR tracking systems; optical homeland security and surveillance. These and many others promising applications are a straightforward consequence of the optical technology progress. As an example, a number of activated materials have been ad-hoc synthesized for the construction of novel optical sources, in both conventional and exotic wavelength ranges, by embedding rare earth ions in different host materials (glass oxides, fluorides, chalcogenides, glass ceramics, crystalline, organics etc.) or by inclusion of rare earth ions in molecular complexes. In addition, novel optical materials as graphene promise novel applications through innovative optical circuitries. The availability of low cost commercial tunable optical sources as quantum cascade lasers and the fabrication of resonant microcavities and microstructured fibers, such as the terahertz sources, allow novel chemical and biological sensing set-ups. Further improvement of sensor performances can be obtained by covering dielectric structures with thin metal layer exploiting plasmon propagation, wavelength resonances and diffraction gratings. Moreover, surprising applications have been originated from the progresses in the field of optical amplification, fluorescent probes, luminescent labels, optical converters, switches, detectors, etc.

One of the most intriguing aspects of the recent applied research is the progressive merging of the aforesaid optical technology with microwave and antenna solutions, for both obtaining access points and complementary physical mechanisms, as expected by the unifying electromagnetic theory, leading to similar engineering approaches.

This Special Issue collects both original contributions and review papers on the optical devices and systems beyond visible, covering an extremely wide area of interest which ranges from telecommunication to optical remote sensing and earth atmosphere monitoring, from medical diagnosis and therapy to material processing, and from aerospace to security. The blending between the technological platforms microwaves/antennas with integrated/fiber optics falls within the Special Issue topics, following the trend of several emerging applications in which these areas are often indistinguishable.
