Extraordinary Transmission and Enhanced Emission with Metallic Gratings Having Converging-Diverging Channels
Extraordinary Transmission Enhanced Emission Metallic Gratings Converging-Diverging Channels
2010/12/6
Transmission metallic gratings having the shape of converging-diverging channel (CDC) give an extra degree of freedom to exhibit enhanced transmission resonances. By varying the gap size at the throat...
Optical Gratings for Electronic Controllable Wavelengthsensitive Switches on Si/SiGe Heterostructures
Optical Gratings Wavelengthsensitive Si/SiGe Heterostructures
2010/7/15
Characteristics of optical gratings on Si/SiGe heterostructures for optical band-pass filters will be discussed. The bandwidth can be down to 0.1 nm. By reducing the refractive index of the SiGe layer...
