“…So far, there have been some proposals to make tunable PCs via mechanical, thermal, biological, and optofluidic methods [5][6][7][8]. Recently, increased efforts have been made using plasma photonic crystals (PPCs) as a special "meta"-material by use of the plasma dispersive properties and the active temporal switching capabilities [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. These have led to some dynamic devices for electromagnetic waves, such as the plasma lens, plasma antenna, plasma stealth aircraft, and so on.…”

“…First, an array of metal electrodes or an array of discharge tubes are utilized to generate periodic plasma columns whose symmetries are * fanweili@hbu.edu.cn right commensurate with the artificial structures [10][11][12][13][14][15]. Second, PPCs are fabricated either by inserting an arrangement of solid rods (dielectric or metal) into the plasma background, or in reverse, producing periodic plasma rods in a solid background [17,18]. Third, PPCs are achieved by introducing the plasma elements into a crystal cavity structure as point defects [19][20][21].…”

Spatiotemporally Controllable Plasma Lattice Structures in Dielectric Barrier Discharge

A method to generate spatiotemporally controllable plasma lattice structures via dielectric barrier discharge is proposed by utilizing a latticed water electrode. A variety of plasma lattice structures including triangle, hexagon, honeycomb, and complex superlattices are obtained by changing three parameters including the applied voltage, the gas pressure, and the gas compositions. Moreover, these plasma lattices can be quickly reconstructed, allowing for active control both in space and time. Two-dimensional particle-in-cell simulations are carried out to demonstrate the formation of plasma structures under different voltages, which are in good agreement with experimental observations. Our method provides a unique way for the fabrication of controllable plasma lattice structures, which may enable tunable control of microwave radiation for wide applications.

“…Previous studies of photonic crystals revealed that the change of air-hole shapes leads to different PBGs. [42,43] Similarly, the Bezier-curve decoration changes the shapes of air holes, modifying in-plane light reflection, that may contribute to the PBG width increase. Furthermore, the proposed Bezier-curve decoration may be replaced by other geometric curves, namely, Euler or Euler-circular curves, to tailor light scattering in the HUDS.…”

Hyperuniform disordered solid (HUDS) structures can provide large, uniform, complete, and isotropic light confinement at the nanoscale after precise design. Based on the HUDS structures, in‐plane light confinement for developing photonic integrated circuits is also explored. To improve the performance of HUDS devices, researchers have mainly focused on cell size or cell distribution optimization in HUDS, which suffers from time‐consuming computation or moderate photonic bandgap (PBG) modification. Here, a morphology engineering method is demonstrated to tailor HUDS PBGs and improve HUDS waveguide devices for transverse electric mode. The results show that the Bezier‐curve‐decorated HUDS devices can achieve a maximum of about 75% PBG width increase, 1.5 dB transmittance improvement in a 10 µm long HUDS waveguide, improved quality factors of HUDS‐cladding microring resonators, and device fabrication compatibility with foundry processing. This study opens new avenues for the development of unprecedented devices for exploring light field regulation, nonlinear optics, and sensing.

“…This has led to the proposal of a new class of nonreciprocal systems based on plasmas, specifically those in the experimentally relevant area of photonic crystals [9]. Prior studies have numerically investigated the band diagram of 1D to 3D plasma photonic crystals with and without magnetization using methods including finite-difference-timedomain (FDTD), transfer matrix method, or plane wave expansion method [10][11][12][13][14][15][16]. A number of experimental works have verified wave interaction with periodic arrays of unmagnetized plasma rods [17][18][19] and demonstrated tunable plasma photonic crystal filters [20,21].…”

Nonreciprocal transport of electromagnetic waves within magnetized plasma is a powerful building block towards understanding and exploiting the properties of more general topological systems. Much recent attention has been paid to the theoretical issues of wave interaction within such a medium, but there is a lack of experimental verification that such systems can be viable in a lab or industrial setting. This work provides an experimental proof-of-concept by demonstrating nonreciprocity in a unit component, a microwave plasma circulator. We design an E-plane Y junction plasma circulator operating in the range of 4 to 6 GHz using standardized waveguide specifications. From both simulations and experiments, we observe wide band isolation for the power transmission through the circulator. The performance and the frequency band of the circulator can be easily tuned by changing the plasma density and the magnetic field strength. By linking simulations and experimental results, we estimate the plasma density for the device.
