Special Issue Information
Dear Colleagues,
The constant downscaling of nanoelectronic and optoelectronic technologies necessitates scientific research on novel micro- or nano-devices in order to create new devices, define generate the complex materials required, and ensure that they have good properties and are reliable.
This Special Issue focuses on, but is not limited to, interface effects, the charge transport process in these nano/micro electronic devices, and the electrical performance improvement of these devices via material and device design and fabrication.
It aims to present the development of state-of-the-art novel micro- or nano-devices. We invite authors from leading groups in the field to contribute original research articles and review articles that cover current micro/nano technologies.
Prof. Dr. Tongbiao Wang

Abstract: We propose a pseudospin hexagonal topological add-drop filter (ADF) and power splitter which can be controlled by magnetic field in this paper. The ADF is constructed by three different geometric parameters of honeycomb lattice with magnetic-optical photonic crystals (MOPCs). The expanded MOPCs with magnetic field have breaking time-reversal symmetry (TRS) and analogous quantum spin Hall (QSH) effect. We use the honeycomb lattice with Dirac points as the waveguide channel and construct the hexagonal photonic crystal ring resonator (PCRR). We have tested the coupling between the waveguide and the resonator in the situation of single-waveguide channel and the dual-waveguide channel at the resonant frequency. Further simulation shows the PCRR has the traveling mode and the standing mode. By applying magnetic field, we use pseudospin-field-dependent waveguide (PFDW) effect successfully control the output of each port at the frequency of traveling mode. When the direction of the magnetic field is changed, we can change the output direction for the upper port. When the size of the magnetic field is changed, we can control the output power of four ports in the PCRR. At this point, we constructed a topological ADF and power splitter. In addition, through simulation, we further demonstrate the robustness of the structure against defects and obstacles. These results have potential in wavelength division multiplexing systems, optical communications and integrated topological optical devices.
