Abstract

We report the first demonstration, to our knowledge, of time-to-space conversion of $1.55\mathrm{\mu m}$ femtosecond optical pulses using nondegenerate, collinearly phase-matched sum-frequency generation. A quasi-monochromatic and background-free output signal spanning a time window of $35\mathrm{ps}$ and with a pulse image width of $350\mathrm{fs}$ was achieved. The resulting serial-to-parallel resolution factor of 100 demonstrates the potential for all-optical complete frame demultiplexing of a $1\mathrm{Tbit}/\mathrm{s}$ optical time-division multiplexing bit stream.
