“…Early sampling systems used directly modulated, gain-switched laser diodes (distributed feedback lasers, DFB) in order to generate short pulses at a MHz-repetition rate [17][18][19][20][21]. These pulse sources, however, produced a rather large timing jitter, which could be reduced by an additional stabilization circuitry using optical holding beams.…”

The optical sampling technique is a novel method to perform time-resolved measurements of optical data signals at high bit rates with a bandwidth that cannot be reached by conventional photodetectors and oscilloscopes. The chapter reviews the techniques that are used in optical sampling systems to perform the ultrafast sampling of the signal under investigation. In addition to the various nonlinear materials and effects used for the optical sampling gates and pulse sources, the realized optical sampling systems also differ in the way, in which the system is synchronized to the data signal. Systems have been reported using synchronous, random and software synchronized configurations. Applications of optical sampling systems include high bit rate waveform and eye diagram measurements, measurements of constellation diagrams of phase modulated data signals, time-resolved measurements of the state-of-polarization as well as investigations of fiber transmission impairments

“…Note that the obtained trace obtained is necessary symmetrical which is leading to a lack of information on the pulse pedestal. Other methods for time analysis with high repetition rate has been proposed in the 90's years such as streak camera [7] and optical sampling [8]. Different approaches have been investigated as all optical sampling using SOA [9] or fiber-based parametric amplification [10].…”

Ultrahigh-speed optical transmission technology, such as optical time domain multiplexing or optical signal processing is a key point for increasing the communication capacity. The system performances are strongly related to pulse properties. We present an original method dedicated to short pulse-shape characterization with high repetition rate using standard optical telecommunications equipments. Its principle is based on temporal measurement of the contrast produced by the beating of two delayed optical pulses in a high-bandwidth photodetector. This technique returns firstly reliable informations on the pulse-shape, such as pulsewidth, shape and pedestal. Simulation and experimental results evaluate the high-sensitivity and the high-resolution of the technique allowing the measurement of pulse extinction ratio up to 20 dB with typical timing resolution of about 100 fs. The compatibility of the technique with high repetition rate pulse measurement offers an efficient tool for short pulse analysis.
