We demonstrate highly sensitive photon counting in the infrared region based on two-
photon absorption (2PA) in a silicon avalanche photodiode, where the required photon …

We show that 2D-decorated silicon nanowires exhibit a strong frequency dependence of the
real (Kerr) and imaginary (two-photon absorption) nonlinear coefficients. In this setting, we …

We present femtosecond pump-probe measurements of the nondegenerate (1960-nm
excitation and 1176–1326-nm probe) two-photon absorption spectra of 8-nm GaAs/12 nm Al …

We derive a novel propagation equation for optical waveguides that properly accounts for
two-photon absorption (TPA). We start from a simple quantum theory of nonlinear fibers …

In this work, we reported two-photon absorption (TPA) measurements for aluminum
vacancies in AlN single crystals. We measured the linear transmission and identified the …

Solitons are nonlinear waves that exhibit persistent propagation in the anomalous
dispersion regime. In this article, we demonstrate the generation of soliton pulse in photonic …

We introduce a silicon squeezer designed for high levels of squeezing and compatibility with
state-of-the-art integrated balanced detection systems. Our approach combines linear …

The significant index contrast between silicon and other CMOS compatible materials
provides substantial obstruction and difficulty in obtaining phase-matching conditions to …
