Frequency-domain phase-conjugate femtosecond pulse generation using frequency resolved crossphase modulation

Abstract

Schemes to generate a frequency-domain phase-conjugate pulse by frequency mixing prechirped pulses are proposed. A femtosecond timereversed replica is generated by the temporal-frequency-converted optical parametric processes.

Spectral phase conjugation via temporal imaging

“…Among these nonlinear effects, SPM typically induces the shortest effective length for practical pulse and fiber parameters [4], which makes SPM compensation more critical than SS or IRS compensation. To date, dispersion compensation by SPC has been demonstrated with spectral and temporal holography [16][17][18][19], three-wave mixing in (2) χ nonlinear media [20,21], cross-phase modulation [22,23], two-photon absorption [24], and photon echo measurements in inhomogeneously broadened media [25,26]. While most of these SPC implementations have focused on GVD compensation, the potential for compensating the higher-order dispersive and nonlinear effects has not been sufficiently exploited.…”

“…The frequency domain phase conjugator (FDPC) generates time-reversed replica of an input pulse [1][2]. For example, the time-reversed replica of a phase-distorted pulse by a GDD element regenerates initial pulse shape after passing though again the same GDD element.…”
