Abstract
An integrated circuit includes a silicon photonics substrate and includes a transimpedance amplifier (TIA) chip and a driver chip arranged on the silicon photonics substrate. The silicon photonics substrate includes a silicon-based material, includes electrical connections, and includes silicon photonics components configured to receive and transmit optical signals. The TIA chip includes a silicon-germanium material that is different from the silicon-based material, is connected via the electrical connections to at least one of the silicon photonics components configured to receive an optical signal, and is configured to process a received optical signal and to output a processed signal to a digital signal processor. The driver chip includes CMOS material that is different from the silicon-germanium material and the silicon-based material, and is connected via the electrical connections to drive at least one of the silicon photonics components configured to generate an optical signal for transmission.
