“…The development of nanophotonic circuitry depends greatly on advance in modulation schemes configuration ( Figure 4). Therefore, plasmonic switching devices form one of the most promising directions in nanophotonics, as it aims to employ SPP waves in semiconductor structures to control the properties of different nanodevices [114][115][116][117][118][119][120][121][122][123][124][125][126][127]. For a typical absorption modulator, it is convenient to introduce the logarithmic ER per unit length [128]:…”

Abstract:The ongoing quest for ultra-compact optical devices has reached a bottleneck due to the diffraction limit in conventional photonics. New approaches that provide subwavelength optical elements, and therefore lead to miniaturization of the entire photonic circuit, are urgently required. Plasmonics, which combines nanoscale light confinement and optical-speed processing of signals, has the potential to enable the next generation of hybrid information-processing devices, which are superior to the current photonic dielectric components in terms of speed and compactness. New plasmonic materials (other than metals), or optical materials with metal-like behavior, have recently attracted a lot of attention due to the promise they hold to enable low-loss, tunable, CMOScompatible devices for photonic technologies. In this review, we provide a systematic overview of various compact optical modulator designs that utilize a class of the most promising new materials as the active layer or corenamely, transparent conducting oxides. Such modulators can be made low-loss, compact, and exhibit high tunability while offering low cost and compatibility with existing semiconductor technologies. A detailed analysis of different configurations and their working characteristics, such as their extinction ratio, compactness, bandwidth, and losses, is performed identifying the most promising designs.

“…This simplifies the integration of electro-optic polymer with silicon platform which provides the ability to design ultra-high speed devices with low energy consumption. So far, for example, this approach has been employed to realize ultra-compact and high-speed electro-optic switch [10] and intensity modulator [11] based on directional coupler. In addition, a hybrid plasmonic WRR modulator based on MOS capacitor has been proposed for optical intensity modulation [12].…”

In this paper, we propose an ultra-compact highspeed electro-optical modulator with extremely low energy consumption based on silicon-polymer-metal hybrid plasmonic waveguide. Spatial confinement of the optical mode of the hybrid plasmonic waveguide and its dependence on small refractive index changes of the polymer is exploited to control the resonance wavelength in a coupled waveguide ring resonator structure and realize optical intensity modulation. Our theoretical exploration and numerical simulations show that with proper design of the hybrid plasmonic waveguide, modulation speed of over 1 THz with modulation depth of ∼8 dB and extremely low energy consumption of ∼3.6 fJ/bit is achievable in a structure with overall footprint in the order of 11 μm 2 .

“…In the past decades, diverse effects have been studied and used in plasmonic modulators such as carrier dispersion effect in silicon [5][6][7], in indium tin oxide (ITO) material [8][9][10][11], insulator-metal phase transition in vanadium dioxide [12][13][14], thermo-optic effect [15][16][17], Franz-Keldysh effect [18], reorientation of ferroelectric domains [19] and electro-optic Pockels effect [20][21][22][23][24][25][26][27][28][29][30]. The latter effect showed and proved the best solution providing the phase modulation of the wave in a small length with a high optical bandwidth and high modulating speed, while low power consumption.…”
