Conference on Lasers and Electro-Optics (CLEO) (2012. San Jose, EE.UU.).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.engbook parthttp://dx.doi.org/10.1364/CLEO_SI.2012.CM4M.5http://www.opticsinfobase.org/open access535EngineeringElectrical & ElectronicOpticsApplied PhysicsÓptica (Física)2209.19 Óptica Física
