Abstract

We demonstrate transparent in-contact electrical interconnects over SiN micro-ring resonators using metallic carbon nano-tubes (CNTs). Self-assembled stripes of metallic CNTs are directly in contact with the waveguide operating around 1550nm wavelength. The absorption by the CNTs around 1550nm is negligible for a coverage of about 2 of the micro-ring. The optical performance of the resonator is unaffected till a current density of 35μA�μm. Semi-conducting CNTs with a similar coverage also have negligible absorption around 1550nm. These metallic and semi-conducting CNTs hold promise for the implementation of transparent electronic circuits over SiN-photonic platform. © 2019 Elsevier B.V.
