Our study explores on-chip circuits driven by ultrashort femtosecond pulses, which allow an increased bandwidth of up to 10 THz [1]. The circuits employ macroscopic striplines spanning on the micrometer scale to facilitate the propagation of corresponding electronic pulses. We present a two-temperature heat model investigating the heat dissipation across the metal electrodes in combination with different substrate materials. Such stripline circuits mark a pivotal advancement toward the integration of femtosecond electronics within on-chip quantum circuits.
