The current revolution in information technology is built on the development of semiconductor transistors and electronics over several decades. However, these electronics reached their advancement saturation limit in speed and size. Meanwhile, modern information and communication technology demands higher-speed electronics and faster communications. Hence, the scientific community has started to search for a replacement technology. Recently, the accelerated advancement in ultrafast laser science and technology, including the generation of ultrashort synthesized pulses, has opened the door to the development of ultrafast optoelectronics. For instance, the synthesized field of subcycle pulses allowed demonstrating all-optical switching with attosecond (10 −18 of a second) speed, promising to establish optical transistors with petahertz speed a billion times faster than that of the typical semiconductor transistors. Moreover, controlling the time interval of the switching signals by synthesizing the light field with the attosecond resolution enables digital binary data encoding on ultrafast laser pulses. This advancement would allow transferring data on laser beams for long distances with an enhanced speed of 1 petahertz/s. Here, we present the recent progress and the future of ultrafast optics electronics, their applications in life, and their remarkable potential impact on future technology.

“…where K c = p 2 c /2 and p c are, respectively, the central energy and momentum of the wavepacket, β x is the chirp rate of the XUV pulse and E IR = −∂A IR /(∂t) is the IR electric field. Gagnon and Yakovlev [34] exploited equation (12) to analytically express the bandwidth of the streaked photoelectron wavepacket. This quantity was used for directly extracting the attosecond chirp of the XUV radiation from spectrograms, and the proposed method dubbed Analytical Chirp Evaluation (ACE).…”

“…we obtain analytical expressions for K s and β s in equation (12), which inserted in equation ( 14) give an analytical function describing the experimental spectrogram. We implemented this expression in a nonlinear least-squares curve fitting tool (a Matlab built-in function), which allows retrieving parameters for the XUV and IR pulses by minimizing the distance between the input and reconstructed spectrograms.…”

“…We also applied it to two challenging experimental traces, where common approaches fail. Accessing absolute timings in pump-probe experiments is fundamental for exploiting the extreme temporal resolution of attosecond science, and enables the investigation of lightwave-driven phenomena [12] and the ultrafast interplay of charge, spin, and lattice degree of freedom [13] from which many exotic properties of matter originate.…”

An accurate temporal characterization of both pump and probe pulses is essential for the correct interpretation of any pump-probe experiment. This is particularly true for attosecond spectroscopy, where the pulses are too short to be directly measured with electronic devices. However, when measuring the absolute timing between a light waveform and the related photoinduced physical phenomenon, such characterization does not suﬃce. Here, we introduce a new method called rACE (reﬁned Analytical Chirp Evaluation), which retrieves both pump and probe pulses while establishing a direct relation between the reconstructed time axis and the experimental delay. This feature is particularly relevant for the extraction of absolute time delays, a growing ﬁeld in attosecond spectroscopy. In this work, we prove the robustness of rACE with simulated datasets involving the eﬀect of pulse chirp, distinctive target attributes, and non-isolated attosecond pulses, which normally constitute challenging situations for standard methods. For all the cases reported here, rACE achieves a precise absolute delay calibration with an accuracy better than the atomic unit of time. Its successful application to attosecond experimental measurements makes it a fundamental tool for attaining sub-cycle absolute temporal resolution, enabling new investigations of lightwave-driven ultrafast phenomena.

Unconventional light - matter interaction in the response-time region of unionized bound electrons

In the literature, the experimental studies in laser-bound electron interaction without ionization show us that a specific amount of material-dependent response time must already pass so that the conventional interaction starts afterward and the bound electrons sense the electric field being applied to them. On the other hand, due to the lack of this conventional interaction in the mentioned material-specific response-time region, it is not correct to assume that the material is absolutely transparent to the applied field during this time period, in which we hypothesized that there must be an unconventional light-matter interaction phenomenon. We report the first numerical hypothesis for modeling the mechanism of this phenomenon, of which the interaction procedure has not yet been clearly understood. Our hypothesis very simply modifies the interaction Hamiltonian of the system by embedding an unknown time-varying function that we named the modifier function, proposing that it exists only in the response-time region of the material. The numerical solution in this study proved the existence of the modifier function in the response-time region for the first time. In our humble opinion, this proven phenomenon must be studied and understood more clearly both theoretically and experimentally for each material.
