We propose a time-resolved technique based on coherent intradyne-detection to measure the short-term optical spectral line width and the long-term mode-frequency of a singlemode in a mode-locked laser. Aliasing inherent in self-delayed homodyne technique is avoided.
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 discuss high-speed optical signal processing for telecom applications. We focus on the optical wavelength conversion and self-clocking, respectively. In the optical wavelength conversion, we report 40 Gb/s wavelength conversion that is capable of converting the same wavelength using a single semiconductor optical amplifier. Experimental proofs are presented. In addition, we report a novel self-clocking...
Error free low penalty 650 Gbit/s OTDM transmission is demonstrated using a polarisation independent receiver based on FWM for demultiplexing. Spectral shaping in the transmitter and filtering in the receiver are used for clock extraction.
