WAVE-GUIDE POLARIZER BASED ON RESONANT TUNNELING

We propose a novel and highly efficient waveguide polarizer based on the phenomenon of resonant tunneling. Based on this principle it is possible to fabricate both TE and TM pass polarizers. We show that by proper choice of materials it is possible to obtain TM mode loss greater than 80 dB/mm with a TE mode loss of only 0.5 dB/mm for the TE pass polarizer and TE mode loss up to 24 dB/mm with a TM mode loss less than 0.8 dB/mm for the TM pass polarizer.
