“…This means that this technology would also lend itself favorably to Tbit/s serial communication systems. Very recently, it was thus demonstrated that 1.28 Tbit/s demultiplexing is indeed possible with such a chalcogenide device [24].…”

Wereviewrecent experimental demonstrations of Tbaud optical signal processing. In particular, we describe a successful 1.28 Tbit/s serial data generation based on single polarization 1.28 Tbaud symbol rate pulses with binary data modulation (OOK) and subsequent all-optical demultiplexing. We also describe the first error-free 5.1 Tbit/s data generation and demodulation based on a single laser, where a 1.28 Tbaud symbol rate is used together with quaternary phase modulation (DQPSK) and polarization multiplexing. The 5.1 Tbit/s data signal is all-optically demultiplexed and demodulated by direct detection in a delay-interferometer-balanced detector-based receiver, yielding a BER less than 10−9. We also present subsystems making serial optical Tbit/s systems compatible with standard Ethernet data for data centre applications and present Tbit/s results using, for instance silicon nanowires.

“…Optical-electrical-optical (OEO) interfaces composed of optoelectronic transceivers are limited by the inherent physical speeds and power consumption of electronic [3], and temporal demultiplexing [4]. Dispersion-engineered silicon waveguides have been shown to achieve record-high performances by supporting optical processing at terabit-per-second bit rates [8], and in providing continuously-tunable conversion bandwidth across hundreds of nanometers [9].…”

Abstract-We demonstrate broadband continuous wavelength conversion based on four-wave mixing in silicon waveguides, operating with data rates up to 40 Gb/s, validating signal integrity using bit-error-rate measurements. The dispersion-engineered silicon waveguide provides broad phase-matching bandwidth, enabling complete wavelength-conversion coverage of the -, -, and -bands of the International Telecommunication Union (ITU) grid. We experimentally show this with wavelength conversion of high-speed data exceeding 100 nm, and characterize the resulting power penalty induced by the wavelength conversion process. We then validate the bit-rate transparency of the all-optical process by scaling the data rate from 5 Gb/s up to 40 Gb/s at the 100-nm wavelength conversion configuration, showing consistent low power penalties, validating the robustness of the four-wave mixing process in the silicon platform for all-optical processing.Index Terms-Optical frequency conversion, optical Kerr effect, optical signal processing, silicon-on-insulator technology.

“…In this paper, we propose a scheme that uses photonic chips to perform all-optical signal processing at the nodes of a Tbit/s network [23]. We implemented this scheme demonstrating all-optical signal monitoring and optimization at the transmitter and ultra-fast switching at the receiver using a highly nonlinear dispersion-engineered planar ChG waveguide.…”

We demonstrate chip-based Tbaud optical signal processing for all-optical performance monitoring, switching and demultiplexing based on the instantaneous Kerr nonlinearity in a dispersion-engineered As(2)S(3) planar waveguide. At the Tbaud transmitter, we use a THz bandwidth radio-frequency spectrum analyzer to perform all-optical performance monitoring and to optimize the optical time division multiplexing stages as well as mitigate impairments, for example, dispersion. At the Tbaud receiver, we demonstrate error-free demultiplexing of a 1.28 Tbit/s single wavelength, return-to-zero signal to 10 Gbit/s via four-wave mixing with negligible system penalty (< 0.5 dB). Excellent performance, including high four-wave mixing conversion efficiency and no indication of an error-floor, was achieved. Our results establish the feasibility of Tbaud signal processing using compact nonlinear planar waveguides for Tbit/s Ethernet applications.
