Abstract

Upgraded particle colliders will require high bandwidth readout capable of withstanding extremely high levels of radiation. Optical links Silicon photonics is a promising solution, but conventional high-speed modulators cannot survive radiation damage. Preliminary results show hardening techniques capable of enduring 1 Grad of total ionizing dose, but without yet demonstrating high speed modulation. Ring resonator modulators were designed with various radiation hardness by design techniques and irradiated. Most promising is a highly doped ring resonator modulator with an 18 GHz bandwidth that survived 300 MRad of total ionizing dose.
