Time-to-space conversion of ultrafast optical pulses via spectral nonlinear optics in the 1.5 /spl mu/m band

Summary from only given. Time-to-space conversion enables parallel processing, which maps the serial time-domain input data packet into its spatial replica, and a space-to-time converter following the parallel processor transforms the processed spatial-domain signal back to the corresponding time-domain data. In this work, we emphasize the time-to-space converter as a step towards the full space-time processing system. we report the first spectral nonlinear optics time-to-space converter operating in the 1.5 /spl mu/m optical communications band. The use of second harmonic generation (SHG) as the spectral nonlinear optical process provides ultrafast response.
