“…The particle is trapped by one of the high intensity evanescent fringes in the MMI, while by changing the relative electric field intensity between the two inputs of the MMI we could modify the location of the fringes, and by that to shift the position of the nanoparticle along the air gap, similar to what occurs with optical tweezers. 7,13 Please note that the assembly of the nanoparticles inside the air gaps (in both methods) is performed by using FIB technology. According to the method reported in Ref.…”

“…Several devices that are based on manipulation of nanoparticle have already been demonstrated. A tunable y-coupler, which allows controlling the propagation of light inside a photonic structure, 1 all-optical nanomodulator, 2,3 sensor, 4,5 wavelength converter, 6 logic gate, flip flop, 7,8 and nanophotonic electro-optical modulator that, according to the position of the nanoparticle inside an air gap, controls whether the propagating signal will reach the output of the device or not. 9 In order to cascade those aforementioned devices, a unique mass production method for assembling nanoparticles into a specific area on the chip has been developed.…”

The hybrid optically and electrically controllable field effect transistor is a novel device whose current-voltage (I-V) curve can be controlled by optical or electrical modulation of metallic nanoparticles. The basic structure of this transistor is similar to that of a junction gate field effect transistor, where the conventional gate contact is replaced by an array of nanoparticles located on the upper side of the p-n junction and parallel to the channel direction, whereas the source and the drain contacts remain the same. The deposition of the nanoparticles is achieved by self-assembly using the focused-ion-beam technology. The displacement of the nanoparticles along the air gap is performed either optically or electrically. Optical control is based on a special type of optical tweezers realized by guiding and confining light into a nanosize void structure in which the nanoparticle is placed. Electrical control via an external electric field tunes the nanoparticles. Control of the I-V curve controls the logic function of the device.

“…This generic relationship has been particularly encountered in coupled photonic/electronic devices 1 2 3 4 5 . For example, an interesting new concept for realizing nanometric photonic devices on silicon chips focuses on implanting a single gold nanoparticle (Au NP) along the silicon waveguide while externally controlling its photonic tunability 6 7 . In another recent demonstration, realization of optically reconfigurable properties was obtained by illumination of metal nanorod assemblies 8 .…”

Generation of macroscopic phenomena through manipulating nano-scale properties of materials is among the most fundamental goals of nanotechnology research. We demonstrate cooperative “speckle beats” induced through electric-field modulation of gold (Au) nanorods embedded in a transparent sol-gel host. Specifically, we show that placing the Au nanorod/sol-gel matrix in an alternating current (AC) field gives rise to dramatic modulation of incident light scattered from the material. The speckle light patterns take form of “beats”, for which the amplitude and frequency are directly correlated with the voltage and frequency, respectively, of the applied AC field. The data indicate that the speckle beats arise from localized vibrations of the gel-embedded Au nanorods, induced through the interactions between the AC field and the electrostatically-charged nanorods. This phenomenon opens the way for new means of investigating nanoparticles in constrained environments. Applications in electro-optical devices, such as optical modulators, movable lenses, and others are also envisaged.
