Paper Abstract

For the next-generation ultra-high-speed TDM optical communication systems, we are developing a waveguide type digital optical pulse synthesizer based on the time-to-space conversion. Our digital optical synthesizer can produce arbitrary optical packets with high bit rate in the order of 100 Gbps and chirp-free pulses. In the early prototype, the signal for controlling the phase and the amplitude of optical signal was manually adjusted with trial and error. Recently, we have introduced a feedback system to this synthesizer for automatic generation of controlling signal, which makes it extremely easier to produce optical signal with arbitrary shape. In this paper, we demonstrate experimental generation of Fourier-transform limited optical pulses and arbitrary 8-bit RZ pulse packets with a bit rate of 100 Gbps.
