“…After each round trip half of the signal continues its propagation inside the loop, the remainder is coupled out for monitoring. The measurements are performed with a linear optical sampling setup [24] which enables us to record the nonlinear evolution of the signal power profile with high temporal resolution over the complete propagation distance. Such a detailed experimental insight in nonlinear pulse propagation in discrete systems is, at present, unattainable in equivalent spatial arrangements [5,6,25].…”

We experimentally demonstrate the formation and stable propagation of various types of discrete temporal solitons in an optical fiber system. Pulses interacting with a time-periodic potential and defocusing nonlinearity are shown to form gap solitons and nonlinear truncated Bloch waves. Multipulse solitons with defects, as well as novel structures composed of a strong soliton riding on a weaker truncated nonlinear Bloch wave are shown to propagate over up to eleven coupling lengths. The nonlinear dynamics of all pulse structures is monitored over the full propagation distance which provides detailed insight into the soliton dynamics.

“…One approach to monitor the phase of an optical data signal directly is the measurement of constellation diagrams [7] by means of coherent homodyne linear optical sampling [51]. In this sampling technique, samples of the electric field (i.e.…”

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

“…Using multiple 40 GHz phase modulations of a CW laser, MSTAR [6] has reached nm-scale accuracy. More recently Coddington et al [7] have demonstrated a laser ranging scheme that efficiently combines time-of-flight and interference measurements in a single measurement inspired from optical linear sampling [8]. The laser source, however, may require significant engineering to be space qualified.…”

-We present a laser ranging system, under development, that uses a high frequency modulated beam to achieve sub-nm resolution by the combined use of interferometric and time-of-flight measurements. We first describe how the absolute distance is extracted from a two-mode interference signal. In particular we show that the signal, which presents both optical and synthetic wavelength scales, is essential to achieve nm-scale accuracy, despite the significant long-term phase drifts in the 20 GHz detection chains. Then we present results obtained with the telemeter implemented on an optical table, for a distance of about four meters, implemented by folding the laser beam path to the target. The challenge here is to achieve a phase and amplitude measurement of two 20 GHz signals with a resolution well below 10 -4 cycle and 10 -4 , respectively, despite the fact that the signal undergoes very strong ( 3 × ) amplitude changes.
