“…For the shifted structure, the maximum power can be achieved for the optimal values of offset at the different junction, in contrast to the structure without offset. In consequence, the dimension of the curved structure is decreased to 1380µm which is compatible with integrated optics trends [25].…”

The S-Bend structures are heavily exploited to join optical components. Reducing the power loss caused by the curve is the main objective in the design step of these components. However integrated optical circuits require S-Bend waveguide to be low loss and compact sized. In this paper, we present a contribution to link the curved structure to the straight waveguide by using the simulated bend function available in the Beam propagation tool of the Rsoft commercial software package. Simulation results confirm that this approach allows a reduction of the size of the curved structure with offset with relatively minimum of losses for photonic field.

“…To some extent, the changes of the crystal orientation are equivalent to varying the incident angle of the EM waves, which may have significant influence on the photonic band diagrams. It was proven in previous studies that a blue shift of the photonic bands as well as a narrowed band gap is achieved when increasing the incident angle of the EM waves [42]. Thus, through modulating the orientation of the plasma structures, we suggest an alternative way to control the reflection and transmission behavior of the EM waves.…”

We demonstrate a kind of structural tunable plasma photonic crystal in a dielectric barrier discharge by self-organization of the plasma filaments. The symmetry, the lattice constant and the orientations of different plasma photonic crystals can be deliberately controlled by changing the applied voltage. The plasma structures can be tuned from a square lattice to a triangular lattice, the lattice constant is reduced and the crystal orientation varies π6 when the applied voltage is increased. The band diagrams of the plasma photonic crystals under a transverse-magnetic wave have been studied, which shows that the positions and sizes of the band gaps change significantly for different plasma structures. We suggest a flexible way for the fabrication of tunable plasma photonic crystals, which may find wide application in the manipulation of microwaves or terahertz waves.
