Abstract

A novel fiber-optic device acting simultaneously as a polarizer and a directional coupler is fabricated by coating a metal layer onto the fused biconical-taper structure of single-mode fibers. This polarizing directional coupler exhibits an extinction ratio of 15 dB together with a 1:1 power-splitting ratio and an excess loss of 2.8 dB.
