    Lumerical Solutions 2d eigenmode simulations using lumerical solutions
    ( A ) <t>3D</t> illustration of device concept. Light is delivered to the nanoscale device via a photonic waveguide, while the Au contacts serve as both device electrodes and plasmonic nanogap to focus incoming light. ( B ) Optical and ( C and D ) SEM images of device after fabrication {scale bar [inset of (C)], 100 nm}. The width of the nanogap was measured to be approximately 50 nm for the devices used. ( E ) Eigenmode simulations of field enhancement inside the plasmonic nanogap when the GST is in the amorphous (top) or crystalline state (region between Au electrodes, bottom). The field enhancement is much stronger when GST is in the amorphous state owing to the significantly lower optical loss. ( F ) <t>FDTD</t> simulation of the transmission of device before and after crystallization. The significant change in the refractive index changes the coupling between the nanogap and waveguide, which reduces reflection from the input waveguide, thereby increasing overall transmission of the device in the crystalline state. ( G ) Experimental measurement of total energy in the waveguide required to achieve a nonvolatile phase transition. The switching threshold was measured to be 16 ± 2 pJ according to a linear fit to the data (black dashed line).

    Article Snippet: To quantify the field enhancement of the plasmonic nanogap, we performed both 2D eigenmode and 3D finite-difference time-domain (FDTD) simulations using Lumerical Solutions and plot the field profile cross sections of the device when GST is in the amorphous and crystalline phases (see ).
