Special Issue Information

Dear Colleagues,

In recent decades, surface-wave-based devices have attracted the attention of researchers worldwide due to their unique characteristics and applications in the field of medical diagnostics, engineering optics and environmental monitoring. The complete potential of these devices can be utilized by integrating surface waves with photonic crystal technology, which provides an edge because of their light-controlling phenomena. This provides an alternative to the conventional Surface Plasmon Resonance (SPR) technique, with improved functionality and better design control. Thus, with this technique, we can focus on the generation, manipulation and confinement of lights along with novel surface-wave-based applications such as microscopic imaging, fluorescence spectroscopy, wave guiding, filters and sensors.

This Special Issue aims to provide a platform to exchange recent breakthroughs and future perspectives related to surface-wave-assisted PhC-based devices. All types of research and review papers presenting novel research ideas based on either theoretical or experimental insights are welcomed. The topics of interest include but are not limit to:

  • The design and fabrication of PhCs;
  • Bloch-surface-wave-assisted PhCs;
  • Quasi-periodic photonic devices;
  • Tamm-Mode-assisted PhC devices;
  • Dielectric surface wave resonator;
  • Surface wave guiding;
  • Surface mode localization effect;
  • Bio/chemical-sensing and bio-imaging;
  • Filters.

In this work, a dielectric photonic crystal-based thermal sensor is numerically investigated for the near-infrared spectral range. An easy-to-fabricate design is chosen with a waveguide layer deposited on a silicon dioxide substrate with air holes drilled across it. To sense the ambient temperature, a functional layer of polydimethylsiloxane biguanide polymer is deposited on the top, the optical properties of which vary with changes in the temperature. An open-source finite-difference time-domain-based software, MEEP, is used for design and numerical simulation. The design of the sensor, spectral properties, and proposed fabrication method are part of the discussion. The performance of the sensor is investigated for an ambient temperature range of 10 to 90 °C, for which the device offers a sensitivity value in the range of 0.109 nm/°C and a figure-of-merit of 0.045 °C−1. Keeping in mind the high-temperature tolerance, inert chemical properties, low material cost, and easy integration with optical fiber, the device can be proposed for a wide range of thermal sensing applications.

In this paper, the localization of optical interface edge-states is analyzed for a dielectric material-based quasi-periodic photonic crystal (QPhC) structure. The design comprises a bilayer PhC structure, where layers are arranged in a Fibonacci configuration to introduce quasi-periodicity. The impact of local symmetric sub-structures on Eigenstate coupling is considered over a wider wavelength range. This confirms the localization of interface edge modes for different wavelengths at the structural local resonators, where the number of local resonators depends on the length of the QPhC. The proposed seven-element QPhC structure shows a strong Tamm-like top interface edge mode localization for a 45.04° incident angle at 750 nm operating wavelength, whereas a bulk interface guided mode is also excited for a higher incident angle of around 79°. The investigation facilitates the development of reconfigurable devices to excite both bulk interface and surface interface edge modes with improved field intensities for spectroscopy and sensing applications.
