Ultrafast all-optical processor for time-to-two-dimensional space conversion by using second harmonic generation

We describe an ultrafast all-optical processor for time-to- 2-D-space conversion by using a second harmonic generation. We show the proposed technique for ultrafast all-optical processor that can convert a modulated ultra-short optical pulse sequence into a 2-D spatial distribution for ultrafast spatial information processing with ultra-short pulse laser. Experimental results show the proposed processor can achieve the throughput of conversion over Tbps.
