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, Manuel Arturo Méndez-Rosales +5
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…
