Femtosecond pulse shaping by dynamic holograms in photorefractive multiple quantum wells.

چکیده
Femtosecond pulses can be shaped in the time domain by diffraction from dynamic holograms in a photorefractive multiple quantum well placed inside a Fourier pulse shaper. We present several examples of shaped pulses obtained by controlling the amplitude or the phase of the hologram writing beams, which modifies the complex spectrum of the femtosecond output.

Real-time edge enhancement of femtosecond time-domain images by use of photorefractive quantum wells.
Dynamic holograms written in a photorefractive multiple quantum well placed inside a Fourier femtosecond pulse shaper convert a space-domain image into the time domain. We demonstrate that edge-enhancement processing of the time-domain image can be performed by controlling hologram-writing intensities.
متن کاملBandwidth-Limited Diffraction of Femtosecond Pulses from Photorefractive Quantum Wells - Quantum Electronics, IEEE Journal of
The diffraction of 100-fs pulses from the static gratings of photorefractive quantum wells (QW’s) produces diffracted pulses that are nearly transform-limited, despite the strong dispersion near the quantum-confined excitonic transitions. This quality makes the QW’s candidates for use in femtosecond pulse shaping, although the currently limited bandwidth of the quantum-confined excitonic transi...
متن کاملTime-Domain Image Processing Using Dynamic Holography
Coded ultrafast optical pulses can be treated as onedimensional (1-D) images in the time domain. We have converted space-domain images into time-domain images using diffraction from dynamic holograms inside a Fourier pulse shaper, with photorefractive quantum wells (QW’s) used as the dynamic holographic medium. We present several examples, in which amplitude or phase modulation of the hologram ...
متن کاملBroadband low-dispersion diffraction of femtosecond pulses from photorefractive quantum wells
Photorefractive quantum wells operating by means of the Franz–Keldysh effect were designed to diffract a bandwidth of approximately 8 nm, nearly matching that of 100-fs pulses, with little dispersion in the diffracted pulses. Large diffraction bandwidths are engineered by adjustment of the well width of the quantum wells in a specific nonuniform distribution across the thickness of the device. ...
متن کاملBandwidth study of volume holography in photorefractive InP:Fe for femtosecond pulse readout at 1.5 mm
The Bragg selectivity of volume holograms makes them not well suited for many Fourier imaging processing applications in the space domain because they perform the function of a spatial filter and limit the field of view. Similarly, for femtosecond pulse holography they reduce the spectral bandwidth of the diffracted signal. However, we show both theoretically and experimentally that it is much ...
