Ultrafast optics has undergone a revolution in the past two decades, driven by new methods
of pulse generation, amplification, manipulation, and measurement. We review the …

Since the first demonstration of the quantum cascade laser (QCL) frequency comb in 2012,
there have been open questions concerning the reproducibility of comb states, and, critically …

We report the complete spatio-temporal characterization of ultrashort light pulses using a
self-referencing device based on shearing interferometry in the space and frequency …

In this paper, we extend the recently introduced linear technique for temporal phase
reconstruction using optical ultrafast differentiation (PROUD) to achieve full characterization …

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 …

We present a heterodyne measurement of the spectral amplitude and phase of periodic
optical signals. In contrast to previous techniques this measurement requires no optical …

We show that the method of complete optical field reconstruction introduced by Debeau et
al.[Opt. Lett. 23, 1784 (1998) 10.1364/OL. 23.001784] allows a precise determination of the …

Swept coherent optical spectrum analysis is becoming a viable method for subpicometer
spectral characterization of optical communications signals. The performance of this …

A novel method to measure a relative phase between frequency-different optical
wavelengths has been proposed and named as Dual-heterodyne-mixing method. The …

The complete characterization of a short light pulse requires the measurement of the value
of the electric field as a function of time, or conversely, as a function of the optical frequency …
