We demonstrate an AO-OFDM system with a WSS-based transmitter and time-lens based receiver for spectral magnification, achieving BER∼10−9 for a 28×10 Gbit/s DPSK AO-OFDM signal. Furthermore, the receiver performance for DPSK and DQPSK is investigated using Monte Carlo simulations.
To ensure that ultra-high-speed serial data signals can be utilised in future optical communication networks, it is indispensable to have all-optical signal processing elements at our disposal. In this paper, the most recent advances in our use of non-linear materials incorporated in different function blocks for high-speed signal processing are reviewed.
We demonstrate a 10 GHz 680 fs pulse source tunable over the C-band, based on a CW laser, 10-GHz LiNb03-modulators and fibre-based SPM compressors. The pulses are used to generate error-free 640 Gbit/s OTDM data.
We describe methods to generate and optically signal process Tbaud serial optical data signals. We present sub-systems making serial optical Tbit/s systems compatible with standard Ethernet data for data centre applications, and present Tbit/s results using a.o. silicon nanowires.
We propose chip-based Tbaud processing for all-optical performance monitoring, switching and demultiplexing. We demonstrate the first transmitter optimization and receiver-end demultiplexing of 1.28 Tbit/s OOK signals. Both exploited Kerr nonlinearity in dispersion-engineered As2S3 planar waveguide.
Error free low penalty 650 Gbit/s OTDM transmission is demonstrated using a polarisation independent receiver based on FWM for demultiplexing. Spectral shaping in the transmitter and filtering in the receiver are used for clock extraction.
Polarization insensitive 320 Gb/s RZ-DQPSK single channel wavelength conversion was demonstrated using a Ti:PPLN-waveguide as all-optical wavelength converter in a bidirectional mode of operation. Error free performance of the converted signal was achieved.
We present a single-channel 1-Tb/s transmission system based exclusively on semiconductor pulse sources. By using alternating polarization RZ-DQPSK modulation a record transmission length of 480-km dispersion managed fiber is achieved.
The linewidth of an improved 40 GHz modelocked laser diode is investigated. The influence of its operation parameters on linewidth and the resulting performance in a 40Gband-DQPSK system is evaluated.
We present a 53.5 GHz monolithic pulse source, applied as transmitter in a single-channel, 107 Gb/s RZ-DQPSK system with 100 GHz filtering. Error-free transmission over 480 km was demonstrated.
