Erbium-implanted tellurite waveguides with low-temperature post-implantation activation and signal enhancement

Yuxuan Gao, Batoul Hashemi, Bruno L. Segat Frare +7

In this paper, we demonstrate erbium ion implantation and signal enhancement in tellurium oxide hybrid waveguides. Silicon nitride strips with a width of 2 m and a height of 100…

Silicon photonic paper-clip spiral delay lines with ultra-low delay loss of 0.5 dB/ns

Batoul Hashemi, Manuel Arturo Méndez-Rosales, Parimal Edke +4

In this work, we demonstrate compact paper-clip spiral silicon photonic waveguides with ultra-low delay loss. We characterize the optical loss and group delay of single-mode and mu…

Surface acoustic waves Brillouin photonics on a silicon nitride chip

Yvan Klaver, Randy te Morsche, Roel A. Botter +14

Seamlessly integrating stimulated Brillouin scattering (SBS) in a low-loss and mature photonic integration platform remains a complicated task. Virtually all current approaches fal…
