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

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 CMOS-platform compatible TM-polarizer.
