Difference-frequency generation in optically poled silicon nitride waveguides

Rui Ning Wang, Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Edgars Nitiss, Ozan Yakar, Boris Zabelich, Ezgi Sahin

Difference-frequency generation (DFG) is elemental for nonlinear parametric processes such as optical parametric oscillation and is instrumental for generating coherent light at long wavelengths, especially in the middle infrared. Second-order nonlinear fr ...

Difference frequency generation in optically poled silicon nitride waveguides

Camille Sophie Brès, Edgars Nitiss, Ozan Yakar, Boris Zabelich, Ezgi Sahin

All-optical poling leads to an effective second-order nonlinearity (chi((2))) in centrosymmetric materials without the need for sophisticated fabrication techniques or material processing, through the periodic self-organization of the charges. The absence ...

Thermo-optically tunable spectral broadening in a nonlinear ultra-silicon-rich nitride Bragg grating

Ezgi Sahin

Spectral tunability methods used in optical communications and signal processing leveraging optical, electrical, and acousto-optic effects typically involve spectral truncation that results in energy loss. Here we demonstrate temperature tunable spectral b ...
