Special Issue Information

Dear Colleagues,

Thermal radiation and micro-/nanophotonics is one of the most active frontiers in the development of optics, combining achievements in both photonics and nanotechnology. It has become an indispensable aspect of science and technology in the 21st century. Its main advantage is that it can achieve many new functions on the basis of local electromagnetic interaction. Thermal radiation and micro/nano-photonics is not only one of the leading research directions in the optical field, but is also an important direction of development for new optoelectronic industries. It plays an irreplaceable role in optical communication, interconnection, and storage; sensing imaging and measurement; display; solid-state lighting; biomedicine; security; green energy; and other fields.

The rapid growth of thermal radiation and micro-/nanophotonics has benefited from the continuous quest to design and build innovative nanostructures. At present, there is a strong interest in exploring the unconventional properties and advantages offered by alternative plasmonic (beyond noble metals), high- or giant-refractive-index, perovskite, quantum-confined (two- or three-dimensional), and hybrid nanostructures.

In this Special Issue, we aim to provide a timely perspective on the advances in thermal radiation and micro-/nanophotonics related to such novel nanostructures. The topics to be covered include (but are not limited to) the following:

  • Fabrication of nanostructures;
  • Optical properties of nanostructures;
  • Nanostructured metamaterials: fabrication and optical properties;
  • Biosensing based on surface plasmon resonance;
  • Interactions between laser and matter;
  • Applications, e.g., sensing, photocatalysis, photovoltaics, lighting, and switching.

We look forward to receiving your contributions.

This paper presents a photonic crystal fiber (PCF) sensor that can be used to measure the temperature and magnetic field simultaneously, and to monitor the changes in them in the environment. When we designed the fiber structure, two circular channels of the same size were added to the fiber to facilitate the subsequent addition of materials. A gold film is added to the upper channel (ch1), and the channel is filled with a magnetic fluid (MF). The sensor can reflect changes in the temperature and magnetic field strength. The two channels containing MF and PDMS in the proposed fiber are called ch1 and ch2. The structure, mode and properties (temperature and magnetic field) were analyzed and discussed using the finite element method. By using the control variable method, the influence of Ta2O5 or no Ta2O5, the Ta2O5 thickness, the diameter of the special air hole, the distance from the fiber core and the distance between them in the displacement of the loss spectrum and the phase-matching condition of the coupling mode were studied. The resulting maximum temperature sensitivity is 6.3 nm/°C (SPR peak 5), and the maximum magnetic field sensitivity is 40 nm/Oe (SPR peak 4). Because the sensor can respond to temperature and magnetic field changes in the environment, it can play an important role in special environmental monitoring, industrial production and other fields.
