Recent results on parametric amplification in the Frequency domain are presented followed by elaborating future designs of all Yb based high repetition rate FOPA chains.
We characterized a dipole response with an inner shell induced by an isolated attosecond pulse. We reconstruct the dipole response from the spectral interferogram constructed with two fields of electromagnetic radiation in a neon atom.
We review our progress in the characterization of the nonlinear transmission properties of low loss germanium-on-silicon waveguides. Simple pump-probe experiments are employed to demonstrate their use for all-optical control.
Space-division multiplexed (SDM) systems use multiple spatial-paths to increase the capacity carried by an optical fiber. The ability to integrate spatial-paths enables the SDM versions of components such as optical amplifiers to provide significant cost and efficiency advantages over the alternative, duplicated single-mode fiber systems.
We have proposed high-speed pre-equalizing electro-optic modulators, which can compensate for signal distortion caused by fiber dispersion utilizing velocity-mismatched traveling-wave electrode and polarization-reversed structures. Pre-equalization for 40Gb/s QPSK signals using double Mach-Zehnder waveguides is presented.
Plasma diagnosis revealed that the electron density of an optical-field-induced Ar2* amplifier was larger than 1018 cm−3 after 100 ns of the plasma production, which resulted in the 126 nm optical gain of 1.1 cm−1.
