Generation of 20-Gb/s RZ-DQPSK Signal using a Directly Modulated Chirp Managed Laser
Generation RZ-DQPSK Signal Directly Modulated Chirp Managed Laser
2015/5/21
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...
200-Gb/s, 430-km PDM-RZ-DQPSK (4 bit/symbol) Transmission with 10 krad/s Endless Polarization Tracking
Fiber Optic Communications Polarization
2015/6/8
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...
Wide Dynamic Range OSNR Monitoring for RZ-DQPSK Systems using Delay-Tap Sampling Technique
Fiber optics communications Fiber optics links subsystems
2015/6/5
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...
FWM-based All-Optical Phase Drop for Format Conversion from 320-Gb/s RZ-DQPSK to 160-Gb/s RZ-DPSK
Phase Drop Format Conversion RZ-DQPSK RZ-DPSK
2015/7/20
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...
Wide Range Over 20 dB Output Power Control Using Semiconductor Optical Amplifier for 43.1 Gbps RZ-DQPSK Signal
Output Power Control Semiconductor Optical Amplifier RZ-DQPSK Signal
2015/7/15
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...
Precise Analysis of Transmission Impairments of Pol-Mux 110Gb/s RZ-DQPSK with Automatic Pol-Dmux using Straight 2,000-km SMF Line
Transmission Impairments Automatic Pol-Dmux
2015/7/31
Transmission of Pol-Mux 110Gb/s RZ-DQPSK signal with automatic Pol-Dmux at receiver over straight 2,000-km SMF line with +3dBm/ch shows that the performance is mainly governed by OSNR and PMD.
53.5 GHz Monolithically Integrated Pulse Source for 107 Gb/s RZ-DQPSK Transmission
Monolithically Integrated Pulse Source RZ-DQPSK Transmission
2015/7/31
We present a 53.5GHz monolithic pulse source, applied as transmitter in a single-channel, 107Gb/s RZ-DQPSK system with 100GHz filtering. Error-free transmission over 480km was demonstrated.
111-Gb/s POLMUX-RZ-DQPSK Transmission over 1140 km of SSMF with 10.7-Gb/s NRZ-OOK Neighbours
POLMUX-RZ-DQPSK Transmission SSMF NRZ-OOK Neighbours
2015/7/30
We demonstrate the transmission of 111-Gb/s POLMUX-RZ-DQPSK over an 1140 km EDFA-only link in the presence of 10x10.7-Gb/s OOK neighbours and show the impact of channel spacing on the cross-talk.
