The core, substrate, and cladding of the polarization rotator are InGaAsP, SiO 2 , and SiO 2 /air materials, respectively, suitable in an InP-based membrane technology. The effects of several parameters such as refractive index of core, the ratio of the width to height of the polarization rotator, and wavelength of incident light on the rotation angle, polarization conversion length, and polarization conversion efficiency are investigated. The simulation results show that the rotation length is \1 lm at 1.55 lm wavelength and a maximum rotation of 89°can be achieved to have a linear polarization at the output end of polarization rotator.
