Operating at the telecommunication wavelength of 1.55 <formula formulatype="inline"><tex Notation="TeX">$mu{rm m}$</tex></formula>, the rotation length is very short <formula formulatype="inline"><tex Notation="TeX">$({rm 3.2}~mu{rm m})$</tex></formula>, while the polarization conversion efficiency is as high as 99.5%. The total device insertion loss is only 1.38 dB, much smaller than the common level of plasmonic devices. It also has potential to realize integrated waveplates for various polarization states. 收起
