Fundamental limit of light trapping in grating structures
Solar Energy Nanophotonics and photonic crystals Diffraction and gratings
2010/8/10
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...

Subwavelength Grating Structures Silicon-on-Insulator Waveguides
2009/5/19
First implementations of subwavelength gratings (SWGs) in silicon-on-insulator (SOI) waveguides are discussed and demonstrated by experiment and simulations. The subwavelength effect is exploited for ...

Design of midinfrared photodetectors enhanced by surface plasmons on grating structures
photodetectors enhanced surface plasmons grating structures
2006/8/11
The authors propose to exploit the unique properties of surface plasmons to enhance the signal-to-noise ratio of midinfrared photodetectors. The proposed photodetector consists of a slit in a metallic...
