We present a 2.3-Tbit/s network switching element by exploiting double-pass LCoS technology and bidirectional nonlinear effects inside a single HNLF. We demonstrate 2.3-Tbit/s grooming switch with sim...
We generate 20-Gb/s return-to-zero differential quadrature phase-shift-keying (RZ-DQPSK) signal using a directly modulated chirp managed laser (CML), without requiring any differential encoder and opt...
A 40G RZ-DQPSK transmitter monolithically integrated with a tunable DFB laser array and Mach-Zehnder modulators was developed for the first time. The optical waveform of 40Gb/s DQPSK was successfully ...
Microcavity Saturable absorber is used for phase-preserving amplitude regeneration of RZ-DQPSK signals. The regenerator is assessed in a 28 Gbaud recirculating loop showing system tolerance to nonline...
We experimentally investigate 107 Gb/s 33%-RZ-DQPSK to explore its tolerance towards chromatic dispersion and narrow-band optical filtering. The results indicate that dispersion tolerance can be incre...

We report agile endless optical polarization demultiplex, free of polarization channel jumps, over a 475 Mrad long Poincaré sphere trajectory at 10 krad/s speed, in a 50-Gsymbol/s,4-bit/symbol realtim...
We propose half-symbol delay-tap sampling for OSNR monitoring and extend the monitoring range to 5−45 dB. The proposed method also enables calibration-free monitoring with range of 16−43 d...
We demonstrate long-haul transmission of 50-Gb/s RZ and NRZ-DQPSK signals generated using an electroabsorption-based optical vector modulator. Transmission over 1650 km is achieved with less than 1.2 ...
We demonstrate 40x43Gbit/s NRZ-DPSK and RZ-DQPSK transmission over 1000km of ultra-low-loss G.652 fibre with 200km amplifier spacing. Hybrid contra-directional Raman-EDFA amplification and lumped disp...
We experimentally demonstrated format conversion from 320-Gb/s RZ-DQPSK to 160-Gb/s RZ-DPSK through the proposed all-optical phase drop scheme. It can be applied to drop a binary tributary from a mult...
The performance of injection-current-controlled SOA as output power control device for 43.1 Gbps RZ-DQPSK signal was experimentally investigated. Output power control range over 20 dB, from absorption...
PM-RZ-DQPSK with direct detection and fast optical polarisation tracking achieves 6dB noise margin over a long-haul field link. The crosstalk by 10&40G OOK channels at 50GHz spacing is analysed for hi...
We show error-free wavelength conversion of 86 Gb/s RZ-DQPSK signals with 15 dB gain in a highly non-linear fibre using a dual-pump configuration with precisely counterphased pump-phase modulations.
