COMPREHENSIVE STUDY OF THE WAVE-GUIDE POLARIZER BASED ON THE RESONANT-TUNNELING EFFECT

We examine the thickness of various layers in terms of the dependence of the loss of various modes in a waveguide polarizer based on the res onant tunneling effect. An improved method is proposed to obtain the o ptimum design of such a polarizer. Fabrication tolerances of the desig ned device are also discussed. The study should be very useful in the design of a waveguide polarizer and other devices, such as selective w avelength filters, based on the same principle.
