Abstract In this work we study all-optical multi-channel return-to-zero (RZ)-Con-off keying (OOK) to nonreturn-to-zero (NRZ)-COOK format conversion in single uniform fiber Bragg grating (FBG) for mixed line-rate dense wavelength-division multiplexing systems using mathematical simulations. Forty and 20 Gbit/s RZ-COOK signals with 33% and 50% duty cycles are converted to NRZ-COOK signals in single uniform FBG with 21% reflectivity. Impact of amplitude noise from FBG contrast profile on modulation format conversion efficiency is also studied.
