Compact dipole nanoantenna coupler to plasmonic slot waveguide

“…2(a) and 3(c)]. This value is in good correspondence with the previously reported result [11] except the fact that in our case the excitation spot area is 8 times larger. With the bottom and bottom-and-side reflectors the coupling efficiency is 24% and 26%, respectively [ Figs.…”

“…Optical antennas have been used for fluorescence enhancement and sensing [5], light-emitting diodes [6], lasers [7], photodiodes [8], and solar cells [9], but only recently have nanoantennas been applied to coupling [10][11][12]. In the abovementioned works [10][11][12] dipole or bowtie antennas were used. The maximal reported coupling efficiency (CE), which is the ratio of the power launched into the waveguide to the incident power, of the antenna system [11] for telecom wavelength 1.55 μm was about 15%.…”

The maximal reported coupling efficiency (CE), which is the ratio of the power launched into the waveguide to the incident power, of the antenna system [11] for telecom wavelength 1.55 μm was about 15%. To obtain such CE the light was focused to a small excitation spot with the diameter about 0.9 μm (area of 0.64 μm 2 ) with a high numerical aperture (NA) microscope objective (NA 0.9).…”

Plasmonic mode converter for controlling optical impedance and nanoscale light-matter interaction

“…Recently, prototype nanocircuits using gap nanoantennas [5,6] in connection with plasmonic two-wire transmission lines (TWTLs) have been theoretically proposed [7][8][9] and experimentally studied [10][11][12], showing a realizable approach to the manipulation of electromagnetic field for enhanced spectroscopy [13,14].…”

“…It was shown that CE can be increased to 26% by using additional reflectors [20]. Experimentally measured CE was 15% [21]. optical devices and systems ются в плазмонном волноводе.…”
