Thin-film　lithium　niobate　(TFLN)　is　a　promising　platform　for　optical　communications,　microwave　photonics,　and　quantum　technologies.　Compared　with　conventional　bulk　materials,　the　TFLN　platform　has　received　widespread　attention　for　its　ability　to　achieve　compact　and　high-performance　integrated　photonic　components.　In　this　work,　we　proposed　a　photonic-Assisted　multi-format　microwave　signal　generator　based　on　a　TFLN　Mach-Zehnder　modulator　(MZM).　It　is　a　system　with　the　capacity　to　generate　and　switch　between　a　variety　of　microwave　waveforms　that　are　needed　for　optical　communication　and　radars.　The　proposed　microwave　photonic　link　features　a　simple　architecture,　including　only　a　laser,　an　MZM,　and　a　photodetector　(PD).　Different　waveforms　can　be　obtained　by　appropriately　setting　the　driven　signal　and　direct　current　(DC)　bias　of　the　MZM,　such　as　phase-shift　keying　(PSK)　signal,　amplitude-shift　keying　(ASK)　signal,　and　dual-chirp　microwave　signal.　The　proposed　signal　generator　offers　a　broad　operating　frequency　range　since　no　optical　or　electrical　filters　are　involved.　In　addition,　no　extra　optical　processing　is　required　which　guarantees　the　simplicity　of　the　generator.　©　2023　SPIE.　All　rights　reserved.
