抜粋

The characteristics of the three-guide tapered coupler for an integrated optical isolator with a semiconductor guiding layer (GaInAsP) were experimentally studied. By the experiment for measuring power branching ratio, the unbalance of the ratio smaller than 2% was confirmed for wavelengths ranging between 1.50 and 1.58 μm. The coupling to the central waveguide occurred when two light waves in the side waveguides were in phase. No output was coupled to the central waveguide when they were 180° out of phase. The isolation of more than 17dB will be achieved when the coupler is employed in the isolator.
