High-Speed Pulse Sequences through Semiconductor Optical Nonlinear Amplification and Buried Fiber Propagation

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

Microwave pulse bursts were obtained through optical domain intensity modulated microwave carriers, sliced by cascaded modulator technique, followed by non-linear semiconductor optical amplifier (SOA) pre-chirp. After 3 to 18 km of buried fiber propagation and photo detection, the microwave signals presented increased extinction ratio, up to 36 GHz, with pulse modulation windows from 166 to 1000 picoseconds, achieving rise times near to 10 ps.
