   <dcterms:abstract>Polarization management is a key factor in photonics integration platforms with high birefringence such as Silicon-On-&#xd;
Insulator. Here we design a directional coupler polarization beam splitter composed of two subwavelength waveguides, which&#xd;
only differ in the tilt angle of the silicon segments. Our simulations predict an extinction ratio higher than 20 dB over an&#xd;
86 nm bandwidth with negligible losses. The fabricated device is only 14 μm long, covers a 72 nm bandwidth with sub-decibel&#xd;
insertion losses and exhibits an extinction ratio in excess of 15 dB.</dcterms:abstract>
