Abstract

An ultra-broadband and compact TE-pass polarizer assisted by contra-directional coupling is proposed, which consists of two identical hybrid plasmonic waveguides (HPWs) and a middle strip grating waveguide (SGW). The grating pitch of the SGW is properly designed to make TM polarization satisfy the phase-matching condition. Therefore, the launched TE mode passes through the middle SGW directly with a very low propagation loss, while the launched TM mode is contra-directionally coupled to the two HPWs evenly and finally absorbed by the top metal layers. Simulation results show that the proposed polarizer has a compact coupling length of $\sim\!{16.48}\;{\rm \unicode{x00B5}{\rm m}}$, and the insertion loss, extinction ratio, and reflection loss are 0.269 dB, 27.7 dB, and $ - {16.5}\;{\rm dB}$ for the fundamental TE mode at 1550 nm, respectively. In the wavelength range of 1430–1700 nm, the ER is more than 20 dB and the IL is less than 1 dB, extending the operating spectrum to 270 nm.
