Here we design a directional coupler polarization beam splitter composed of two subwavelength waveguides, which only differ in the tilt angle of the silicon segments. Our simulations predict an extinction ratio higher than 20 dB over an 86 nm bandwidth with negligible losses. The fabricated device is only 14 μm long, covers a 72 nm bandwidth with sub-decibel insertion losses and exhibits an extinction ratio in excess of 15 dB. spa open access Circuitos integrados-Diseño y construcción Fotónica Silicio sobre aislante Sistemas de comunicación inalámbricos Polarización Microelectrónica-Materiales Separador de polarización integrado de altas prestaciones basado en estructuras sub-longitud de onda conference output
