Abstract: We demonstrate an in-line fiber-optic polarizer using resonant tunneling through a leaky multilayer overlay for the first time. Polarization extinction ratio (PER) 27 dB with an insertion loss (IL) 3 dB has been demonstrated experimentally with scope of further improvement. A simple planar waveguide model is developed to analyze the device whose predictions match very well with the experimental results. It is further shown that by properly selecting the device parameters one can achieve PER 68 dB with IL 0.2 dB for λ = 0.6328 μm and PER 80 dB with IL 1.2 dB for λ = 1.3 μm.
