- Polarization dependent light extraction of a GaN light emitting diode using dark field angle-resolved photoluminescence spectrometryChih Ming Wang
Department of Opto electronic Engineering, National Dong Hwa University, Hualien, 97401 Taiwan
Opt Express 20:17952-61. 2012..The ARPL spectrum also reveals that the extraction efficiency is relatively high as the dispersion line of the waveguide mode is coincident with the folded free-photon dispersion of the 1D GaN grating...
- Spatial filtering by using cascading plasmonic gratingsChih Ming Wang
Institute of Opto electronic Engineering, National Dong Hwa University, Hualien, Taiwan 97401, ROC
Opt Express 17:6218-23. 2009..The angular dispersion of the cascading plasmonic gratings is about d theta/d lambda =0.15 degrees/nm. The cascading plasmonic gratings can be used as a spatial filter to improve the spatial coherence of a light source...
