Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue on the "Recent Advances in Micro/Nanofabrication and Optical Devices" in our journal. Micro/nanofabrication has been rapidly advancing in recent years, driven by the demand for smaller and more efficient devices in various fields such as electronics, photonics, and biotechnology. The ability to fabricate structures with feature sizes on the micro/nanometer scale has enabled the development of novel advanced optical devices with unprecedented capabilities and performance. For example, metasurfaces in particular have received significant attention for their ability to manipulate light at the nanoscale, allowing for the creation of ultra-compact devices such as optical displays, imaging, and communication. Therefore, micro/nanofabrication-driven optical devices will lead to the great development of ultra-compact optical systems. This Special Issue aims to facilitate the exchange of ideas and knowledge in this exciting field and showcase the latest research achievements.

The aim of this Special Issue is to present the recent advances in micro/nanofabrication and optical devices, including but not limited to novel micro/nanofabrication techniques, new optical devices, and emerging applications. The Special Issue will also explore the challenges and opportunities associated with the development of optical micro/nanofabrication and devices. Submissions should align with the scope of our journal and contribute to advancing the understanding of this field.

We welcome original research articles, reviews, and perspectives that address the following areas:

  • Advances in micro/nanofabrication techniques;
  • Design, fabrication and performance analysis of micro/nano optical devices;
  • New materials for micro/nanofabrication and micro/nano optical devices;
  • Emerging applications of micro/nanofabrication and optical devices;
  • Challenges and opportunities in the development of micro/nanofabrication and optical devices.

We look forward to receiving your contributions and publishing a collection of high-quality articles that will advance the field of optical micro/nanofabrication and devices.

The main purpose of this study is to design combinational logic gates based on a novel configuration of insulator–metal–insulator (IMI) nanoring plasmonic waveguides. Plasmonic logic gates are half adder, full adder, half subtractor, full subtractor, and one-bit comparator and are realized in one structure. The performance of the logic circuits is based on constructive and destructive interferences between the input and control signals. The transmission threshold value is assumed to be 0.35 at the resonance wavelength of 1.310 μm. The transmission spectrum, contrast loss (CL), insertion loss (IL), modulation depth (MD), and contrast ratio (CR) are calculated in order to evaluate the structure’s performance. The maximum transmission of the proposed structure is 232% for full a adder logic gate, and MD exceeds 90% in all plasmonic combinational logic circuits. The suggested design plays a key role in the photonic circuits and nanocircuits for all-optical systems and optical communication systems. The combinational logic gates are analyzed and simulated using the finite element method (FEM). Full article
