We present the first 320Gb/s all-optical clock recovery by exploiting single Quantum Dash MLL to generate 40GHz synchronized optical clock pulse with 71fs timing jitter. 320Gb/s all-optical demultiplexing operation with 1dB BER penalty was demonstrated.
We report first demonstration of quantum dash mode-locked laser based open-loop optical clock recovery of 160 Gb/s RZ-OOK after 52 km transmission with 102 fs timing jitter 40 GHz clock and 2 dB BER penalty.
We demonstrate error-free transmission, dynamic switching and burst detection of 160Gbps packets with guardtime ~1ns through 3-nodes that include on-the-fly optical packet switching and instantaneous locking/unlocking time clock extraction subsystems.
We demonstrate 1 × 4 optical-packet switching with error-free transmission of 640 Gb/s single-wavelength OTDM data-packets including instantaneous clock extraction and short pulse generation for optical time-demultiplexing based on a cavity-less pulse source.
A novel packet clock distribution concept based on insertion of in-band clock pilot is presented. Experimental results for 160 Gbit/s OTDM packet data indicate a low timing jitter of 250 fs for the bursty clock enabling error-free operation with 1 dB penalty.
We demonstrate an all-optical circuit that simultaneously performs packet-by-packet clock recovery (CR) and data demodulation from 10-Gb/s nonreturn-to-zero differential-phase-shift-keying packets. It includes a novel power equalizer based on a nonlinear self-polarization switch in a semiconductor optical amplifier that enables operations within 15-dB input power level fluctuations. Data demodulation...
