Integrated Cu-based TM-pass polarizer using CMOS technology platform

Abstract

-A transverse-magnetic-pass (TM-pass) copper (Cu) polarizer is proposed and analyzed using the previously published two-dimensional Method-of-Lines beam-propagation model. The proposed polarizer exhibits a simulated high-pass filter characteristics, with TM 0 and TE 0 mode transmissivity of >70% and <5%, respectively, in the wavelength regime of 1.2 -1.6 μm. The polarization extinction ratio (PER) given by 10 log 10 (PTM 0 )/(PTE 0 ) is +11.5 dB across the high-pass wavelength regime. To the best of the authors' knowledge, we report here the smallest footprint CMOSplatform compatible TM-polarizer.
