100 Gbit/s optical signal generation by time-division multiplication of modulated and compressed pulses from gain-switched distributed feedback (DFB) laser diode

An all-optical spatial time-division multiplexer is demonstrated using fibre-type 2 × 2 couplers and fibre delay lines. 100Gbit/s modulated optical signals are successfully generated by 32-times multiplication of 3.125Gbit/s, 6ps compressed pulses, from a gain-switched DFB laser diode.
