A pulse-rate-tunable, highly extinctive, ultra-highspeed electrooptic
pulse pattern generator has been developed. The optical short pulse ge
neration is based on sinusoidal electrooptic phase modulation and line
ar chirp compensation using a dispersive medium. Filtering the nonline
ar chirp components generated by sinusoidal phase modulation drastical
ly improves the pulse extinction, and makes nearly background-free pic
osecond pulsation over a wide pulse-rate range even when the group del
ay dispersion value is fixed.
