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 wavelength. The absorption by the CNTs around is negligible for a coverage of about of the micro-ring. The optical performance of the resonator is unaffected till a current density of . Semi-conducting CNTs with a similar coverage also have negligible absorption around . These metallic and semi-conducting CNTs hold promise for the implementation of transparent electronic circuits over SiN-photonic platform. |
