Abstract

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