“…Errorfree operation for both the variable optical buffer and the TSI is demonstrated with 10Gb/s NRZ data packets, revealing power penalty, depending on the integrated delay line used, from 3dB to 5dB. The demonstrated optical delay linebased buffering and TSI configurations report the highest delay efficiency values with respect to required footprint of the delay lines, offering a delay efficiency of 2.6ns/mm 2 that is two orders of magnitude higher than in respective demonstrations so far [7][8][9][10][11][12] with the highest delay being 17.2ns.…”

“…Integrated delay lines have been demonstrated via several alternative integration platforms, exploiting asymmetrical MZIs [6], ring resonators [7], Silica on Silicon integration [8][9], thermo-optics switches on Si3N4 platform [10], polymer waveguides [11] and the InP platform [12]. Nevertheless, most of these demonstrations offer tunable delay in the range of a few hundred ps [6,7,11], limiting their functionality in terms of packet re-arrangement.…”

Abstract-This study presents the recently developed monolithic photonic-integrated circuits that provide efficient amplitude modulation for wavelength division multiplexed optical channels. The circuits were designed for application as a read-out unit in a highenergy physics experiment, and are sufficiently general to be applied in various types of high-speed photonic transmitters. They were constructed using basic building blocks provided in an indium phosphide-based generic integration technology process and fabricated in a multi-project wafer run. Two variants of the circuits, utilizing modulators in Mach-Zehnder and Michelson interferometer configuration, are discussed. A modulation bandwidth of 18.6 GHz was measured and error-free transmission of a 10-Gb/s signal through 85 km of optical fiber was achieved.Index Terms-Electro-optical amplitude modulator (AM), indium phosphide (InP), generic integration technology, MachZehnder interferometer, Michelson interferometer, multi-project wafer (MPW), photonic integrated circuit, wavelength division multiplexing (WDM).

“…The second subsystem is a variable optical delay-line buffer and Time-slot Interchanger module utilizing a set of three on-chip um scale Si-based integrated delay lines with low propagation loss and two, differentially-biased, SOA-MZI based wavelength converters (WC) [26]. The chip-scale SOI delay bank offers variable optical delay that ranges from 6.5 ns to 17.2 ns with a record-high on-chip delay versus footprint efficiency of 2.6 ns/mm 2 , improved by almost one order of magnitude compared to the 0.38 ns/mm 2 state of the art implementations, featuring at least 10 ns on-chip delay [27][28][29][30][31][32][33][34]. This integrated variable SOI-based delay bank along with two WCs are utilized for the demonstration of a variable optical buffering scheme at 10 Gb/s, while the largest on-chip delay line of 17.2 ns is shown to perform successfully also in a 10 Gb/s optical TSI demonstration that uses two additional delay lines formed by fibers and two WC modules.…”

Abstract:In this paper, we demonstrate two subsystems based on Silicon Photonics, towards meeting the network requirements imposed by disaggregation of resources in Data Centers. The first one utilizes a 4 × 4 Silicon photonics switching matrix, employing Mach Zehnder Interferometers (MZIs) with Electro-Optical phase shifters, directly controlled by a high speed Field Programmable Gate Array (FPGA) board for the successful implementation of a Bloom-Filter (BF)-label forwarding scheme. The FPGA is responsible for extracting the BF-label from the incoming optical packets, carrying out the BF-based forwarding function, determining the appropriate switching state and generating the corresponding control signals towards conveying incoming packets to the desired output port of the matrix. The BF-label based packet forwarding scheme allows rapid reconfiguration of the optical switch, while at the same time reduces the memory requirements of the node's lookup table. Successful operation for 10 Gb/s data packets is reported for a 1 × 4 routing layout. The second subsystem utilizes three integrated spiral waveguides, with record-high 2.6 ns/mm 2 , delay versus footprint efficiency, along with two Semiconductor Optical Amplifier Mach-Zehnder Interferometer (SOA-MZI) wavelength converters, to construct a variable optical buffer and a Time Slot Interchange module. Error-free on-chip variable delay buffering from 6.5 ns up to 17.2 ns and successful timeslot interchanging for 10 Gb/s optical packets are presented.
