Photonic chip based 1.28 Tbaud Transmitter Optimization and Receiver OTDM Demultiplexing

Single- and multi-carrier techniques to build up Tb/s per channel transmission systems

“…5.1 Tb/s PDM-DQPSK at 1. 28 Tbaud has also been demonstrated with error-free performance (BER < 10 -9 ) in a standard direct detection DxPSK receiver [17]. Very recently, it has been demonstrated that optical non-linear effects in compact devices can be harnessed and used for Tb/s switching, e.g.…”

“…Very recently, it has been demonstrated that optical non-linear effects in compact devices can be harnessed and used for Tb/s switching, e.g. using a chalcogenide (ChG) waveguide and a silicon nanowire [28,29]. These results, together with semiconductor optical amplifier based demultiplexers [30,31], show great promise for making compact multifunctional optical chips with ultra high-speed potential.…”

Demultiplexing techniques of 320 Gb/s OTDM-DQPSK signals: A comparison by simulation

“…However its stability is still a serious obstacle. Recently, nonlinear waveguides have emergd as a promising device for ultra-high speed photonic processing [7] [8]. This device is very compact and the FWM is exploited for demultiplexing as shown in Fig.…”

Extreme OTDM

“…Time domain demultiplexing of a 1.28 Tbit/s OOK signal by four wave mixing (FWM) in a compact 7 cm long chalcogenide glass wave guide was demonstrated in [6]. Error free and low penalty demultiplexing was achieved as well as signal quality monitoring allowing for optimisation of the optical multiplexer.…”
