RT Book, Section T1 Ultra-Compact Polarization Mode Converter Implemented in a Dual-Trench Silicon-On-Insulator Waveguide A1 Villafranca Velasco, Aitor A1 Calvo Padilla, María Luisa A1 Cheben, Pavel A1 Ortega Moñux, Alejandro A1 Schmid, Jens H. A1 Alonso Ramos, Carlos A1 Molina Fernández, Íñigo A1 Lapointe, Jean A1 Vachon, Martin A1 Janz, Siegfried A1 Xu, Dan-Xia AB We demonstrate an ultracompact polarization mode converter based on a silicon-on-insulator waveguide with two longitudinal subwavelength trenches. An extinction ratio of 16 dB at 1.5 μm is achieved for a device length of 10 μm.
