Special Issue Information
Dear Colleagues,
This Special Issue will focus on intriguing sensing approaches for developing probes used in bio/chemical sensing. These methods include the utilization of plastic optical fibers (POFs), specialty optical fibers, metasurfaces, and optofluidics. For instance, there is a significant interest in using innovative POF-based extrinsic or intrinsic schemes, such as “MathMaterial interfaces” combined with POF probes for machine and deep learning in bio/chemical sensing approaches. Moreover, using different receptor layers combined with optical probes to detect specific substances in different application fields is equally intriguing. This Special Issue wants to collect research manuscripts or review manuscripts about POF-based platforms, metasurface-based sensors, optofluidic-based sensor systems, and biosensors or chemical sensors implemented by extrinsic or intrinsic optical fiber schemes and using specific (biomimetic, biological, or chemical) receptor layers or machine and deep learning approaches.

Abstract: Existing tunable optical metasurfaces based on the electro-optic effect are either complex in structure or have a limited phase modulation range. In this paper, a simple rectangular metasurface structure based on the Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) crystal with high electro-optic coefficient of 120 pm/V is designed to demonstrate its electrically tunable performance in the optical communication band through simulations. By optimizing the structure parameters, a tunable metasurface is generated that can induce a complete 2π phase shift for beam deflection while maintaining relatively uniform transmittance. Simulations further demonstrate the electrical tunability of the beam deflection direction and operating wavelength of the metasurface. This tunable optical metasurface, with its simple and easily fabricated structure, can promote the development and application of multifunctional and controllable metasurfaces. Its adjustable beam deflection direction and operating wavelength may find applications in fields such as optical communication systems and imaging.
