Satellite communication is a crucial technology to complement terrestrial wired and mobile networks, such as provided by 4G/5G and optical fiber. The applications driving the need for more bandwidth are the same for SATCOM as for common terrestrial telecom. However, space-specific challenges exist due to the radiation environment and stringent Size, Weight, and Power consumption (SWaP) constraints. Therefore, linearly expanding the payload of a satellite is not possible to stay within a realistic launchable volume and mass. While optical fiber technology was introduced in terrestrial networks for its high-capacity, long-distance capabilities, it now provides an attractive solution for short intra-satellite links due to its reduced size and mass compared to bulky RF waveguides. The current space-grade components are limited in availability and speed compared to their terrestrial counterparts. The challenge lies in optimizing front-end electronics for both radiation tolerance and electro-optic co-design. Our goal is to improve existing "bent-pipe" satellite architectures by designing multi-channel electronic and photonic integrated circuits (EIC/PIC) featuring a small footprint and high energy efficiency for space-grade radio-over-fiber (RoF) links operating in the V-band. In addition, new architectures will be studied for frequency translation, like mixing in the optical domain using an optical phase-locked loop (OPLL).
