Abstract
An arrayed waveguide for a photonic integrated circuit has a single optical path with serially connected delay lines. Different delayed optical paths or channels are periodically split off from the serially connected optical delay path. This has the net result of requiring much less space on-chip for comparable optical path differences with high spectral resolution.
