Abstract

An ultra-compact hybrid plasmonic mode convertor is demonstrated based on a hybrid plasmonic slot waveguide structure. Benefiting from the unidirectional eigenmode expansion approach, a mode-interference-based ${{\rm TE}_{00}}$-to-${{\rm TM}_{01}}$ mode convertor is realized for the first time, to the best of our knowledge, with an ultra-compact footprint of only ${2}.{33} \times {7}\,\,\unicode{x00B5} {{\rm m}^2}$. At the wavelength of 1550 nm, the insertion loss is below 2.34 dB, and the extinction ratio is 25.6 dB with mode conversion purity as high as 94.6%. The extinction ratio is over 15.5 dB for the entire C-band with a bandwidth of extinction ratio above 10 dB larger than 110 nm. The transmissivity of the crosstalk ${{\rm TE}_{10}}$ and ${{\rm TE}_{02}}$ at 1550 nm is $ - {16.1}$ and $ - {22.7}\,\,{\rm dB}$, respectively.
