TLDR
In this paper, the authors show that the overall losses, power consumption and the footprint of plasmonic electro-optic modulators can be reduced when a device is operated in the vicinity of absorption resonances of an electrooptical material.Abstract:
The electro-optic coefficient (Pockels coefficient) is largest around the absorption resonance of a material Here, we show that the overall losses, the power consumption and the footprint of plasmonic electro-optic modulators can be reduced when a device is operated in the vicinity of absorption resonances of an electro-optical material This near-resonant operation in plasmonics is contrary to what is known from photonics where off-resonant operation is required to minimize the overall losses The findings are supported by experiments demonstrating a reduction in voltage-length product by a factor of 3 and a reduction in loss by a factor 2 when operating a plasmonic modulator near resonance compared to off-resonantread more

TL;DR: Ohmic losses in plasmonic devices can be reduced by exploiting ‘resonant switching’, in which light couples to surface plAsmon polaritons only when in resonance and bypasses them otherwise.

TL;DR: In this article, the authors demonstrate that plasmonic modulators do not trade-off any performance parameter, featuring a short length of tens of micrometers, record-high flat frequency response beyond 500 GHz, high power handling, and high linearity, and use them to create a sub-terahertz radio-over-fiber analog optical link.
