In this letter, we investigate a tapered coupler for efficient coupling of light between a planar HIMI plasmonic and dielectric waveguides. The coupler gives an overall transmission efficiency of 98% at optical wavelength of 1550 nm. It offers long propagation length 328 $$\mu \hbox {m}$$ at the mode propagation loss of 0.0132 dB/ $$\mu \hbox {m}$$ . The coupler’s efficiency has also been investigated with respect to its important parameters. The entire structure occupies a footprint area of 3 $$\times$$ 1.2 $$\mu \hbox {m}^2$$ and it is CMOS compatible with on-chip applications.
