Optical time-division multiplexing (OTDM) is potentially a useful technique for increasing the bit rate of a system beyond the bandwidth capabilities of drive electronics. Here we report progress on a novel optical multiplexing scheme using mode-locked extended cavity injection lasers and TI:LiNbO3 waveguide switch/modulators. We demonstrate OTDM of two separate lasers that are mode-locked and encoded at 2 GHz. The 4-Gb/s multiplexed signal is transmitted over 8 km of fiber.
