2R optical regenerator in As_(2)Se_(3) chalcogenide fiber characterized by a frequency-resolved optical gating analysis

摘要

We present a detailed analysis of a 2R optical regenerator based on self-phase modulation in As_(2)Se_(3) chalcogenide glass fiber using frequency-resolved optical gating (FROG). We obtain good agreement between the FROG measurements and theory, and confirm that the output pulses are near-transform limited. We show that two-photon absorption improves the profile of the power transfer function while not degrading the temporal performance.
