Of all oxides, lithium niobate (LiNbO_3) is the gold standard electro-optical material in fiber-
optic transmission systems. Modulators based on diffused waveguides in bulk LiNbO_3 …

Silicon photonics is a technology based on fabricating integrated optical circuits by using the
same paradigms as the dominant electronics industry. After twenty years of fervid …

Typical integrated optical phase tuners alter the effective index. In this paper, we explore
tuning by geometric deformation. We show that tuning efficiency, Vπ L, improves as the …

Microresonator-based frequency comb generation at or near visible wavelengths would
enable applications in precise optical clocks, frequency metrology, and biomedical imaging …

Silicon photonics, considered as a major photonic platform for optical communications in
data centers, is today also developed for others applications including quantum photonics …

Although silicon does not possess a dipolar bulk second order nonlinear susceptibility due
to its centro-symmetric crystal structure, in recent years several attempts were undertaken to …

We investigate the influence of the wavelength, within the 1.3 μm–1.63 μm range, on the
second-order optical nonlinearity in silicon waveguides strained by a silicon nitride …

Second-order optical effects are essential to the active control of light and the generation of
new spectral components. The inversion symmetry, however, prevents achieving a bulk χ (2) …

Nonlinear optics is an important and exciting field of fundamental and applied research, with
applications in many different disciplines such as physics chemistry, material science and …

The observation of the electro-optic effect in strained silicon waveguides has been
considered a direct manifestation of an induced χ^(2) nonlinearity in the material. In this …
