Archimedean spiral waveguide as a phase shifter for Optical Phased Arrays

Resumo

© 2021 IEEE.Silicon nanophotonics is contributing to develop devices with small dimensions and low energy consumption. In space systems, whether in large or small satellites, such as CubeSat the demand for photonic devices has been growing, especially in the communication subsystem. For CubeSat the need to develop optical communication devices with reduced dimensions, low energy consumption and a precision aiming system, with no movable parts, is a challenge. In order to meet these requirements, this article presents a theoretical study on the use of a silicon nanophotonic device, in the form of Archimedean spiral waveguide, for phase modulation in Optical Phased Array antennas.
