    Abstract

    We demonstrate integrated Silicon-on-Insulator (SOI) spiral waveguides with record-high 2.6ns/mm2 on-chip delay efficiency performing as delay bank stage in variable optical delay buffering and Time-Slot Interchanger (TSI) applications with 10Gb/s optical packets. The micro-scale SOI chip comprises three integrated waveguide delay elements of different length, providing variable delays of 6.5nsec, 11.3nsec and 17.2nsec, respectively. Utilizing two SOA-MZI wavelength converters and on-chip packet delay, error-free on-chip variable delay buffering from 6.5nsec up to 17.2nsec and successful timeslot interchanging for 10Gb/s optical packets are presented.
