An applications-oriented review of optical parametric amplifiers in fiber communications is
presented. The emphasis is on parametric amplifiers in general and single pumped …

We propose a terahertz time-domain spectrometer based on asynchronous optical
sampling. The spectrometer features ultrahigh spectral resolution equivalent to a laser mode …

We demonstrate the measurement of waveforms and eye diagrams at high bit rates by
optical sampling using coherent detection. By simultaneously recording two orthogonal …

We review recent research related to polarization mode dispersion (PMD) in fiber-optic
transmission systems operating at 40 Gb/s and above. We investigate the benefits of using …

We demonstrate the characterization of optical sources with high sensitivity, high temporal
resolution, and phase sensitivity using linear optical sampling. Eye diagrams and …

This paper presents the simulation and design of all-optical logic gates OR, AND, XNOR,
and XOR at ultrahigh speed by proposing the semiconductor optical amplifier-Mach …

An all-optical waveform sampling system with simultaneous submilliwatt optical signal
sensitivity (20-dB signal-to-noise ratio) and subpicosecond temporal resolution over more …

This paper describes a software-synchronized all-optical sampling system that presents
synchronous eye diagrams and data patterns as well as calculates accurate Q values …

When there is a need to accurately characterize optical waveforms and, it is not surprising
that some of the best, albeit only recently established, techniques to do this rely on all …

The field of high-speed measurements for optical telecommunication systems is reviewed.
An emphasis is placed on diagnostics evaluating the temporal electric field of light, ie …
