Ultrafast pulse compression by semiconductor two-photon gain.
نویسندگان
چکیده
We demonstrate experimentally the compression of femtosecond-scale pulses by two-photon gain in a compact electrically driven AlGaAs waveguide. Dynamic control of the pulse width from 240 to 140 fs is achieved by varying the current injection levels--in good agreement with the calculations. The pulse width is measured by a high-sensitivity intensity autocorrelator based on two-photon absorption in a GaAs photomultiplier tube.

Complete chirp analysis of a gain-switched pulse using an interferometric two-photon absorption autocorrelation.
We propose a simple but powerful scheme for the complete analysis of the frequency chirp of a gain-switched optical pulse using a fringe-resolved interferometric two-photon absorption autocorrelator. A frequency chirp imposed on the gain-switched pulse from a laser diode was retrieved from both the intensity autocorrelation trace and the envelope of the second-harmonic interference fringe patte...
متن کاملUltrafast photon-number correlations from dual-pulse, phase-averaged homodyne detection
We propose and demonstrate a method for determining the two-time photon-number correlations of an optical field on ultrafast time scales. The method, which uses dual-pulse, phase-averaged, balanced-homodyne detection, is sensitive at the single-photon level and can have a quantum efficiency approaching 100%. Using this method we have determined the two-time, photon-number correlations on subpic...
متن کاملEnergy limits imposed by two-photon absorption for pulse amplification in high-power semiconductor optical amplifiers.
We study the combined effects of dynamic gain saturation and two-photon absorption on the amplification of short pulses in semiconductor optical amplifiers and show that two-photon absorption can saturate the amplifier gain and limit the output pulse energies even for amplifiers with large gain saturation energies. We discuss the upper limits for the pulse energies obtainable from semiconductor...

The high-index contrast between the silicon core and silica cladding enable low cost chip-scale demonstration of alloptical nonlinear functional devices at relatively low pump powers due to strong optical confinement the in silicon waveguides. So far, broad ranges of applications from Raman lasers to wavelength converters have been presented. This presentation will highlight the recent developm...
متن کاملFemtosecond dynamics in semiconductor lasers: Dark pulse formation
We track the dynamic response of GaAs quantum-well semiconductor diode lasers after injection of a femtosecond pulse, using ultrafast upconversion. The continuous-wave emission shows gain dynamics and relaxation oscillations on timescales of 1–100 ps. The recirculating femtosecond pulse evolves into an ultrafast ‘‘dark pulse’’ in the wake of subpicosecond oscillations. © 1998 American Institute...
