We demonstrate successful field trial dual-carrier 400G undersea transmission using 60-GBaud PDM-QPSK modulation format based on digital faster-than-Nyquist shaping on the transmitter side DSP jointed with receiver SOFTN and 20% SD-FEC decoding.
A 32-channel, WDM-PON SFP transceiver is demonstrated at 1.25 Gbps with C-band transmit and L-band receive functionality. The transceiver is based on a wide-band, injection-locked Fabry-Perot laser. Both C-band and L-band SFP transceivers are available.
Subcarrier modulation (SCM) is a promising scheme to implement wavelength division multiplexed passive optical networks (WDM-PONs). We review prior works on SCM-based WDM-PONs, discuss the crosstalk induced as a result of optical carrier reuse, and then present a new architecture for reducing the crosstalk.
A novel architecture for broadcast capable high-speed WDM-PONs is proposed. 40-Gb/s downlink and 10-Gb/s broadcast are demonstrated to transmit simultaneously on the same set of wavelength channels. A colourless 40-Gb/s uplink transmission is also demonstrated with an EAM.
For the first time we demonstrate a fully self-contained photonic transceiver system on a single die with monolithically integrated Ge photo-detectors. The transceiver allows error-free bidirectional 4times10 Gb/s WDM transmission using a single CMOS die at each end of the link.
We demonstrate monolithically integrated 4times10 Gb/s WDM transceivers built in a production 130 nm SOI CMOS process. Only light sources are external to the chip. 40 Gb/s error-free, bidirectional transmission is demonstrated.
We propose and demonstrate a high speed carrier-reuse wavelength division multiplexed passive optical network (WDM-PON) based on injection locked Fabry-Perot laser diodes (FP-LD). Experiments for both downlink and uplink transmission at 10 Gb/s show very good BER performance with a large operating range.
We present novel concepts, technologies and potentials of optical data communication, especially for future computer architectures. The WDM (wavelength division multiplexing) and the optical wiring technologies are explained in detail. Experimental results of tunable optical filters, which play a major role in WDM systems, are reported. New concepts for novel optical interconnectors and novel miniaturized...
We demonstrate tunable dispersion compensation in a 4times40-Gb/s system using sampled NC-FBGs with negligible errors from dispersion slope. The tuning ranges are 400 ps/nm for a single FBG and 600 ps/nm for a twin cascaded-inverse FBG configuration
We demonstrate tunable dispersion slope compensation for 40-Gb/s WDM systems using two inverse 3rd-order chirped gratings. The inherent errors in a single grating are eliminated. The slope range is -20 to +20 ps/nm2over a 5-nm bandwidth.
