Abstract :
Summary form only given. We present a new, highly-efficient, all-semiconductor photorefractive AlGaAs quantum well design in which all the defects have been removed from the cladding layers. Output diffraction efficiencies approaching 40% have been achieved in this design, an order of magnitude greater than demonstrated in all previous designs.
