“…Besides hybridizing the WGM and LSPR mode, many other possible combinations of plasmonic and photonic modes can be considered. For example, the hybridization of photonic crystal cavity (PCC) and some plasmonic elements such as metal films or metallic nanostructures has been widely investigated [748][749][750][751][752][753][754][755][756][757][758][759][760] and experimentally demonstrated for sensing [761][762][763][764][765][766]. De Angelis et al proposed and experimentally demonstrated such a hybrid plasmonic-photonic sensor consisting of a plasmonic nanoantenna sitting in the center of L3 PCC [761].…”

Optical sensors are widely used for refractive index measurement in chemical, biomedical and food processing industries. Due to specific field distribution of the resonances excited, optical sensors provide high sensitivity to ambient refractive index variations. The sensitivity of optical sensor is highly dependent on material and structure of the sensor. Here, we review six major categories of optical refractive index sensors using plasmonic and photonic structures: (i) metal-based propagating plasmonic eigenwave structures, (ii) metal-based localized plasmonic eigenmode structures, (iii) dielectric-based propagating photonic eigenwave structures, (iv) dielectric-based localized photonic eigenmode structures, (v) advanced hybrid structures, and (vi) 2D material integrated structures. Representative configurations working in the wavelength range of 400−2000 nm will be selected and compared in terms of bulk refractive index sensitivities, figure of merits and working wavelengths. A technology map is established in order to define the standard and development trend for optical refractive index sensors.

2D-ordered dielectric sub-micron bowls on a metal surface: a useful hybrid plasmonic–photonic structure

et al. 2016

Recently, it has been demonstrated that the combination of periodic dielectric structures with metallic structures provides an efficient means to yield a synergetic optical response or functionality in the resultant hybrid plasmonic-photonic systems. In this work, a new hybrid plasmonic-photonic structure of 2D-ordered dielectric sub-micron bowls on a flat gold surface was proposed, prepared, and theoretically and experimentally characterized. This hybrid structure supports two types of modes: surface plasmon polaritons bound at the metallic surface and waveguided mode of light confined in the cavity of bowls. Optical responses of this hybrid structure as well as the spatial electric field distribution of each mode are found to be strongly dependent on the structural parameters of this system, and thus could be widely modified on demand. Importantly, compared to the widely studied hybrid systems, namely the flat metallic surface coated with a monolayer array of latex spheres, the waveguided mode with strong field enhancement appearing in the cavities of bowls is more facilely accessible and thus suitable for practical use. For demonstration, a 2D-ordered silica sub-micron bowl array deposited on a flat gold surface was fabricated and used as a regenerable platform for fluorescence enhancement by simply accommodating emitters in bowls. All the simulation and experiment results indicate that the 2D-ordered dielectric sub-micron bowls on a metal surface should be a useful hybrid plasmonic-photonic system with great potential for applications such as sensors or tunable emitting devices if appropriate periods and materials are employed.

“…However, as stand-alone elements, plasmonic modulators suffer from unfavorable trade-offs between footprint, losses, and extinction ratios. On the other hand, the demonstration of Si-VO 2 hybrid planar optical switches utilizing surface plasmons propagating between silver and VO 2 [16,17], among other hybrid plasmonic-photonic structures [23,24], suggests that it may be possible to overcome these tradeoffs, although the switching demonstrated in the Si-VO 2 hybrid structure was slow (~25 µs) because the phase transition was initiated by heating [16,17].…”

Hybrid Si-VO_2-Au optical modulator based on near-field plasmonic coupling

et al. 2015

View full text Add to dashboard Cite

We present a computational design for an integrated electro-optic modulator based on near-field plasmonic coupling between gold nanodisks and a thin film of vanadium dioxide on a silicon substrate. Active modulation is achieved by applying a time-varying electric field to initiate large changes in the refractive index of vanadium dioxide. Significant decrease in device footprint (200 nm x 560 nm) and increase in extinction ratio per unit length (9 dB/µm) compared to state-of-the-art photonic and plasmonic modulators are predicted.
