Abstract :
We propose an arrayed-waveguide grating with a built-in interferometer that enables us to evaluate the amplitude and phase distribution in the arrayed waveguides easily and precisely. We fabricated the proposed optical circuit with silica waveguides, and successfully confirmed its operational principle in experiments.
