TL;DR: This letter deals with the analysis of an MGDM point-to-point link, transparent to the transmission format, using subsets of propagating modes to minimize crosstalk among the channels.
Abstract: Mode group diversity multiplexing (MGDM) is an optical multiple-input-multiple-output technique that aims at creating independent communication channels over a multimode fiber, using subsets of propagating modes. This letter deals with the analysis of an MGDM point-to-point link, transparent to the transmission format. The geometry of a mode-group selective multi/demultiplexer is optimized in order to minimize the crosstalk among the channels. The power penalty is calculated when a zero-forcing algorithm is used to mitigate the crosstalk

TL;DR: In this article, a hybrid-integrated all-optical flip-flop, where InP-based semiconductor optical amplifiers are assembled onto a planar silica waveguide board, is demonstrated.
Abstract: A fully-packaged hybrid-integrated all-optical flip-flop, where InP-based semiconductor optical amplifiers are assembled onto a planar silica waveguide board, is demonstrated. It is shown experimentally that the flip-flop can dynamically toggle between its two states by injecting 150 ps optical pulses with 6 dBm peak power via its set and reset port

TL;DR: In this article, the flip-flop can have its state changed dynamically every 32ns with the introduction of state-setting pulses (pulse widths ≪150ps).
Abstract: We describe a novel, fully-packaged, hybrid-integrated all-optical flip-flop memory element. Static state contrast ratios of 10dB and 13dB are demonstrated and the flip-flop can have its state changed dynamically every 32ns with the introduction of state-setting pulses (pulse widths ≪150ps).

TL;DR: In this paper, the authors demonstrate error-free 160 Gb/s optical wavelength conversion employing a single semiconductor optical amplifier. But the gain recovery time of the optical amplifier is greater than 90 ps.
Abstract: We present some progress in the field of optical signal processing that could be utilized in all-optical packet switching. We demonstrate error-free 160 Gb/s optical wavelength conversion employing a single semiconductor optical amplifier. The gain recovery time of the semiconductor optical amplifier is greater than 90 ps. Assisted by an optical bandpass filter, an effective recovery time of 3 ps is achieved in the wavelength converter, which ensures 160 Gb/s operation. This optical wavelength converter can be controlled by a monolithically integrated optical flip-flop memory to route 80 Gb/s data-packets all-optically. The routing is realized without electronic control. The integrated optical flip-flop is based on two-coupled lasers, exhibits single-mode operation, has 35 dB contrast ratio between the states and switches state in about 2 ns. We demonstrate that the integrated flip-flop is able to control the optical wavelength converter up to 160 Gb/s. The system is capable of routing 80 Gb/s data packets with duration of 35 ns, separated by 15 ns of guard time.
