Title: Planar multiple-tapped optical delay line

Abstract: Photonic signals of high bandwidth are input into a planar spiral of waveguide. The spiral has a number of waveguide loops having a series optical tap areas wherein optical energy is leaked from the loops. The leaked optical energy is received by optical tap waveguides that carry the light for further processing.
