SOA-based fiber ring laser use in a photonic radio-frequency phase shifter

摘要

This investigation demonstrates the feasibility of a semiconductor optical amplifier (SOA)-based fiber ring laser use in a photonic radio-frequency (RF) phase shifter. Experimental results indicate that a fiber ring laser can successfully replace an external pump laser in a photonic RF phase shifter. The RF phase shifter can be turned by adjusting the power of the fiber ring laser.
