Abstract
Optical pulses with time separation corresponding to bit rates of ∼ 14 Gbit/s (NRZ) have been produced at λ = 1.32 μm with a Ti: LiNbO3 broadband travelling-wave directional coupler modulator driven by closely spaced, narrow electrical drive pulses. Resolvable optical pulses with as little as 100 ps separation have been generated.
