英文摘要	Conference Name:6th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, NEMS 2011. Conference Address: Kaohsiung, Taiwan. Time:February 20, 2011 - February 23, 2011.; Institute of Electrical and Electronics Engineers (IEEE); IEEE Nanotechnology Council (NTC); National Cheng Kung University; National Tsing Hua University; Chinese International NEMS Socity (CINS); One hexagonal lattice sandwich structure Al/SiO2/Si has been fabricated with different thickness of silicon layer based on Silicon-On-Insulator (SOI) wafer. The transmission spectrum in mid-infrared range is extremely sensitive to the variety of the thickness of silicon layer. An important characteristic is that the number of the coupled modes corresponding to the surface plasmon polaritons (SPPs) model is different with each thickness, especially at 4.08 micrometer, only one coupled mode emerged. This experiment result shows that Localized surface plasmon (LSP) coupled mode and quasi-cylindrical wave (Quasi-CW) resonant mode all have been involved in the enhanced optical transmission phenomenon (EOT), and different coupled mechanisms have strong interaction with each other. The experiment result further reveals the deeper underlying physics of the EOT phenomenon, and is significant to new design of some optical sensor devices based on enhanced optical transmission phenomenon. ? 2011 IEEE.
