Abstract:
All-Optical Networks (AONs) are an active research area for use in Optical Transport Networks (OTNs) and data centers. Adding Optical Time Division Multiplexing (OTDM) to AONs can more efficiently utilize the enormous amount of bandwidth in the fibers. Photonic Timeslot Interchangers (PTSIs) are used in OTDM networks to interchange/switch timeslots. This paper proposes a control algorithm for a previously proposed PTSI that uses multiple feed-forward fiber delay-lines. This algorithm further reduces the required number of delay elements needed for non-blocking operation from the reduction previously reported under a less optimal algorithm. Any reduction in the number of PTSI components should result in increased output signal power, reduced footprint, and reduced manufacturing cost.
