Fig. 2: Calculated distributions of electric fields and heat power densities in Au nanowires.
From: Plasmon-driven nanowire actuators for on-chip manipulation
a, b Electric field distributions of the nanowire–microfibre system at the (upper images) transverse and (lower images) longitudinal sections, excited by a HE11x fundamental mode and b HE11y fundamental mode guided in the microfibre at 1064 nm wavelength. The Au nanowire has a thickness of 100 nm, a width of 200 nm, and a length of 6.0 μm, and the microfibre has a Dfiber of 1.8 μm. Inset of (b) lower image shows the definition of electric field directions. c Absorptance spectra of the Au nanowire with different fundamental modes. d, e Spatial distributions of heat power density on the Au nanowire bottom surface for d the HE11x modes and e the HE11y modes, respectively. f Heat power density value along the sideline (z direction) of the nanowire bottom surface.
