The aim of this work is to design an integrated optical ring resonator to be implemented in LiNbO3 with a 2.5 mm radius and an operating wavelength of 1550 nm. Considering these ring parameters, a free spectral range of 71.54 pm and a quality factor

Compression of 42 fs, 0.29 mJ pulses from a Ti:Sapphire amplifier down to 8 fs (approximately 3 optical cycles) is demonstrated by means of spectral broadening in a compact multi-pass cell filled with argon. The efficiency of the nonlinear pulse comp

In this paper, we propose a new sensing topology based on a differential power analysis, using an array of photonic sensors. The system structure is composed of a 1x4 balanced power divider, three Bragg gratings, and a reference branch. In particular

We present here a theoretical analysis of the interaction between an ideal two-level quantum system and a super-oscillatory pulse, like the one proposed and successfully synthesized in J. Opt. 23, 075604 (2021). As a prominent feature, these pulses p

In this work, we describe an interferometric method to generate ultra-short pulses below the Fourier limit. It is done by extending concepts first developed in the spatial domain to achieve sub-diffractive beams through the addition of a spatial chir

We analyzed the ablation dynamics for Silicon atoms located in two different environments. Experiments were done with semiconductor (silicon wafer) and a dielectric material (fused silica). We point out some difference in plasma dynamics for Silicon
