We report the direct proof of parametric amplification in a semiconductor waveguide. Thanks to low propagation losses and high nonlinear efficiency, we amplified an input signal at 2 μm in a selectively oxidized GaAs/AlAs multilayer waveguide through the down conversion of a pump at 1 μm. The 4.5% single-pass gain measured for a 30 mW cw pump is compatible with parametric oscillation, provided that distributed and concentrated waveguide losses are further reduced.

    Ultrahigh-repetition-rate (over 100 GHz) bound-soliton pulses were experimentally generated in a fiber laser. Through incorporating a Loyt-type filter made of a piece of high birefringent fiber and an intracavity polarizer in a fiber laser, we found that not only ultrahigh-repetition-rate...
