Special Issue Information

Dear Colleagues,

The advancement of nanostructured materials development and the understanding of inclusive photo-physical phenomena have significantly contributed to the advancement of the optoelectronic field. Furthermore, integrating nanomaterials with photonics has paved the way for developing highly efficient nanophotonic devices, which leads to improved interactions between light and matter.

This Special Issue, “Nanostructured Optoelectronic and Nanophotonic Devices”, invites the authors to submit the recent results as original communications, articles, and reviews.

The polarization state of light is critical for biological imaging, acousto-optics, bio-navigation, and many other optical applications. Phase shifters are extensively researched for their applications in optics. The size of optical elements with phase delay that are made from natural birefringent materials is limited; however, fabricating waveplates from dielectric metamaterials is very complex and expensive. Here, we present an ultrathin (14 nm) metallic phase shifter developed using nanoimprinting technology and the oxygen plasma ashing technique for visible and near-infrared wavelengths. The fabrication process can produce desirable metallic phase shifters with high efficiency, large area, and low cost. We demonstrate through a numerical simulation and experiment that the metallic phase shifter exhibits phase delay performance. Our results highlight the simplicity of the fabrication process for a metallic phase shifter with phase delay performance and offer important opportunities for creating high-efficiency, ultrathin polarizing elements, which can be used in miniaturized devices, such as integrated circuits.
