Abstract:
Photonics engineering has been recognised as a Key Enabling Technology-KET with applications in many technological areas. Advances in materials research have enabled the development of new exotic photonic material platforms such as multicomponent glasses and metamaterials with customizable properties that could enable in turn the further development of tailored photonic devices and components. However, further to the fundamental research on those platforms the applicability in real applications is still rather limited as is required considerable amount of research for the development of reliable components required to follow strict operational specifications and standards. In parallel the need for low cost customizable photonic devices, structures and sensors for specific applications requires the efficient exploitation of well-established photonic platforms. Employment of efficient processing techniques and use of specially designed functional materials provides a route that allows the rapid prototyping of customized devices.
Within this frame the talk will present recent and characteristic activities of photonics engineering at NHRF towards the development of customized structures and devices for a wide range of demanding and emerging applications. Theoretical design & modeling issues together with experimental implementations of devices by direct laser writing, micromachining, and thermal processing will be covered. Photonic platforms such as polymer optical fibers, silica or specialty hybrid fibers, silica-based integrated optics, plasmonic and resonating structures, functionalized by nanostructured materials will be presented as examples for a broad range of customized solutions covering application areas from Structural Health Monitoring-SHM, industrial monitoring & predictive maintenance, to defence systems and biomedical applications.
