Graphene, as a novel optoelectronic material, offers great promise to the field of photonics, optical sensors, and a number of other fields. Owing to its superior and intriguing properties, several attractive applications of graphene are being vigorously exploited. However, we believe that the true potential of graphene has not yet been fully exploited. So far, there has been continuous investigation and exploration aiming to answer the new challenges imposed by the different application fields. This has been possible thanks to several factors, including innovation in the function of multiple-graphene–dielectric-graphene layer stacks in a controlled fashion, the improved performance of optical sensors, increased efficiency of interaction of light with graphene, etc.
In this Special Issue, we are aming to focus on the most recent developments in graphene-based photonics and optical devices, covering recent technological improvements in the design, fabrication, and validation of new sensors or the modification of existing ones, and alternative use in emerging applications. We invite you to submit both original research papers and review articles describing the current state-of-the-art in graphene-based photonic and optical sensor technologies.
