Abstract

A hybrid plasmonic waveguide with a metal cap on a silicon-on-insulator rib (or slab) is presented. There is a low-index material nano-layer between the Si layer and the metal layer. The field enhancement in the nano-layer provides a nano-scale confinement of the optical field (e.g., 50nm × 5nm) when operates at the optical wavelength λ = 1550nm. The theoretical investigation also shows that the present hybrid plasmonic waveguide has a low loss and consequently a relatively long propagation distance (on the order of several tens of λ).

Figures (6)

Fig. 1
Fig. 1

The cross section of the present hybrid plasmonic waveguide with a metal cap on a silicon-on-insulator rib. When the height h Si_rib = 0, the Si part becomes a slab waveguide and consequently the fabrication is very easy because the etching becomes shallow.

Fig. 2
Fig. 2

The calculated field distribution for the major component Ey (x,y) of the quasi-TM fundamental mode of the present hybrid plasmonic waveguide with w co = 200nm and h SiO2 = 50nm. In this figure, the field distributions Ey (0, y) and Ey (x, 0) are also shown. One sees that the field at 50nm-SiO2 nano-layer is enhanced greatly.

Fig. 3
Fig. 3

For the cases of h SiO2 = 50 nm, 20 nm, and 5 nm, the real part of the effective refractive index n eff (a), and the propagation distance L prop (b) as core width w co. The insets in Fig. 3(b) show the field distribution of the major component Ey of the quasi-TM fundamental mode for the cases of w co = 100nm, 300nm, and 500nm. One sees that there is more optical field confined in the Si layer when the core width increases. This is why the effective index real(n eff) and the propagation distance L prop increases as the core width increases.

Fig. 4
Fig. 4

For the cases of h SiO2 = 5 nm and w co = 100 nm, the real part of the effective refractive index n eff and the propagation distance L prop as the rib height h Si_rib decreases. When the height h Si_rib = 0, the Si part becomes a slab waveguide, in which case the propagation distance is close to 100μm (~60λ) and the fabrication is very easy because the etching becomes shallow.

Fig. 5
Fig. 5

The field distribution of the quasi-TM fundamental mode with a nano-scale light confinement when h Si_rib = 0, h SiO2 = 5 nm, and w co = 50 nm. The insets show the field distributions Ey (x, 0) and Ey (0, y). One sees that the optical field confinement at the vertical direction is on the order of 5 nm (~λ/300), which is related with the thickness of the low-index nano-layer. At the lateral direction, the optical field confinement is about 50nm (~λ/30).

Fig. 6
Fig. 6

The calculated coupling length as the separation between two parallel hybrid plasmonic waveguides. The waveguide parameters are: h Si_rib = 0, h SiO2 = 5nm (~λ/300), and w co = 50nm (~λ/30).
