Active Plasmonics: Surface Plasmon Interaction With Optical Emitters
... In our first study of active plasmonics, we discuss surface plasmon amplification. Several schemes utilizing various metal geometries and active media have been proposed to achieve surface plasmon amplification. Gain-assisted SPP propagation has been studied in planar metallic films, strips, and gra ...

... The transmission of data using an on-chip OI requires an electro-optical modulator and an electrical driver circuit. The laser source provides light to the modulator, which transduces electrical data supplied from the electrical driver into a modulated optical signal. Several high-speed electro-opti ...

Few-cycle terahertz generation and spectroscopy of nanostructures
... Although photoconductive THz emitters are routinely used for time-domain spectroscopy and THz imaging (Mittleman 2003), there was no attention paid to the improvement of the emitter performance. We have focused on two strategies to optimize the THz emitter. First, with respect to the results of the ...
