Described are a method and a device for high speed transmission of a data signal across an electrical interconnect in an integrated circuit. An optical carrier is modulated with a local oscillator signal at a modulation frequency substantially greater than the data signal to generate an optical local oscillator signal. Phototransducers at the ends of the interconnect illuminated by the optical local oscillator signal generate electrical local oscillator signals. At the transmit end of the interconnect, the data signal is mixed with an electrical local oscillator signal to generate an upconverted data signal. After transmission across the interconnect to the receive end, the upconverted data signal is mixed with the electrical local oscillator signal to retrieve the original data signal.
