The optical bench has been calibrated and it has been verified experimentally that the fluorescent emission from an evanescent wave excited molecule located near the fiber/matrix interface gives rise to a totally internally reflected wave in the fiber-optic waveguide.
Evanescent wave and distal mode experiments were conducted at 60 [degrees] C for both dyes, and the results are compared in Figs 5 and 6.
We have successfully carried out an experimental demonstration of an acoustic hyperlens that magnifies sub-wavelength objects by gradually converting evanescent waves into propagating waves," said Xiang Zhang, a principal investigator with Berkeley Lab's Materials Sciences Division and director of the Nano-scale Science and Engineering Center at the University of California, Berkeley.
As a result of the large ratio between the inner and outer radii, our acoustic hyperlens compresses a significant portion of evanescent waves into the band of propagating waves so that the image obtained is magnified by a factor of eight," said co-author Fok, a graduate student in Zhang's lab.
Surface plasmon resonance (SPR) and related techniques exploiting evanescent waves were developed during the 1980s and used to interrogate biological and chemical interactions between receptors and analytes in real time without labeling the analyte.
The systems will be distressed for steady-state and time-resolved optical measurements of luminescence, reflection and transmission in a variety of samples, as well as measurements of evanescent waves in photonic structures.
