CWDM Planar Concave Grating Multiplexer/Demultiplexer and Application in ROADM
CWDM Planar Concave Grating Multiplexer/Demultiplexer ROADM
2015/5/15
We report a SOI based 1×4 coarse wavelength-division-multiplexer (CWDM) planar concave grating multiplexer/demultiplexer and applications in re-configuration optical add/drop multiplexer (ROADM) syste...
Fundamental limit of light trapping in grating structures
Solar Energy Nanophotonics and photonic crystals Diffraction and gratings
2015/8/10
We use a rigorous electromagnetic approach to analyze the fundamental limit of light-trapping enhancement in grating structures. This limit can exceed the bulk limit of 4n2, but has significant angula...
