Insights on Tuning Directional Quantum Nanophotonic and Waveguiding Energies Through Space and Time: From Nano- to Miniaturized Optics and Instrumentation

Abstract

In this review article, the concept of directional quantum, photonics, and energy emissions from the molecular to the nanoscale and beyond is developed and introduced. In this regard, insights into enhanced phenomena from the nanoscale are presented to be incorporated as a strategy for enhanced phenomena with perspectives of waveguiding signals. Prototyping of hybrid substrates to tune single nano-optics, couple optical components, and add gaining media with diminished optical losses through optically active substrates with perspectives of waveguiding and the generation of directional emissions. Therefore, it is proposed to modulate light propagation highlighting multimodal energies from tuned nanoplatforms with targeted functions, where varied physical phenomena could be proposed to route emissions. Thus, it is proposed to stimulate and show from pioneering phenomena toward recent innovative research focusing on tuning and use of optically active nanoplatforms for the modulation of arrays, assemblies, and conjugated systems with intended directional optical properties. In this context, cutting-edge nanotechnologies and nanophysics were involved. Enhanced phenomena were presented as a strategy for controlled directional properties, affording in this manner as, for example, metal-enhanced fluorescence, fluorescence resonance energy transfer, and coupled phenomena. In this regard, programming photonics toward the design of circuits, modified substrates, and waveguides of different types modified with nanostructured patterns could incorporate enhanced phenomena. The development of enhanced resonances such as enhanced plasmonics and pseudo-electromagnetic fields by carbon-based materials was considered as well to tune faster ballistic photonics through materials.
