The achievement of a 1.51 mu m InAs/InP(3 1 1)B quantum dot (QD) single-mode Fabry-Perot laser operating under continuous wave at room temperature is reported.

We describe a method to study dense wavelength-division multiplexed (DWDM) transmission over amplified links that have no inline dispersion compensation and where the channels have nearly 100% prec

A real-time 56-GBaud PAM-4 serial optical transmission link over 2 km SSMF is demonstrated using in-house developed SiGe PAM-4 driver and clock-and-data recovery ASICs showing BER values down to 2e

We demonstrate a record receiver sensitivity of 2.7 photons per bit at 6.23-Gb/s net data rate using PDM-QPSK with 4-ary-pulse-position-modulation.

We report a field demonstration of transmission of 1.44 Tb/s over the Korean Advanced Research Network (KOREN) using three 341-Gb/s PDM-OFDM signals with 256- iterative-polar-modulation.

We demonstrated for the first time an OOK-NRZ 42.7 Gbit/s WDM system with 0.8 bit/s/Hz spectral efficiency without polarization multiplexing using a single multichannel optical equalizer and optica

A record sensitivity of -36.2 dBm at 1552.5-nm wavelength (45 photons/bit) is reported for an optically preamplified receiver operating at 42.7 Gb/s.

We apply digital back propagation based neural network regression algorithms as the nonlinear equalization approach, and realize up to 50Gbps PAM4 IM-DD PON using 10GHz optics with an overall end-t

Record data rate of 32Gb/s for NFDM transmissions is experimentally demonstrated using 64 overlapping orthogonal 0.5Gbaud channels with 32QAM format, showing a record performance gain of 1.3dB in c

We demonstrate a 1.2 Tb/s optical packet switch fabric based on burst -mode clock -data-recovery at 40 Gb/s with packet separations of up to 400 ns and lock times under 5 ns, fast wavelength switch
