Compact bends for multi-mode photonic crystal waveguides with high transmission and suppressed modal crosstalk
Nanophotonics photonic crystals Integrated optics devices Photonic crystal waveguides
2015/8/7
We demonstrate an extremely compact bend for a photonic crystal waveguide supporting three spatial modes. The bend exhibits nearly 100% transmission over a relative bandwidth of 1% with less than 1% c...
Broadband Sharp 90-degree Bends and T‑Splitters in Plasmonic Coaxial Waveguides
plasmonics coaxial waveguide transmission line bend splitter integrated optical circuit
2015/8/7
We demonstrate numerically that sharp 90°bends and T-splitters can be designed in plasmonic coaxial waveguides at deep-subwavelength scale to operate without reflection and radiation over a broa...

Guided waves Integrated optics devices
2015/6/9
The silicon-on-insulator rib waveguide bends using phase-compensated microprisms are experimental demonstrated. A very compact SOI rib waveguide with bending radius of 15.43μm is achieved with demonst...
Bends and splitters in metal-dielectric-metal subwavelength plasmonic waveguides
Bends splitters metal-dielectric-metal subwavelength plasmonic waveguides
2015/8/11
We investigate the performance of bends and splitters in metal-dielectric-metal subwavelength plasmonic waveguides. We show that bends and splitters with no additional loss over a very wide frequency ...
Bends and splitters for self-collimated beams in photonic crystals

2015/8/12
We demonstrate highly efficient transmission of light around sharp corners in photonic bandgap waveguides. Numerical simulations reveal complete transmission at certain frequencies, and very hig...
Bound states in photonic crystal waveguides and waveguide bends
Bound states photonic crystal waveguides waveguide bends
2015/8/12
We investigate the mechanism for the appearance of bound states in two-dimensional photonic crystal waveguides and contrast it with the corresponding mechanism for conventional guides. It is shown tha...
