  • Abstract
    We report the first Al0.48In0.52As/Ga0.47- In0.53As SAM avalanche photodiode, The device, grown by MBE, has high responsitivity over a wide spectral range (0.85-1.7µm). Avalanche gains of ≅ 27 at low voltages ( l\\sim 30 V) are observed. Fast response with a FWHM of = 250ps and no tails are observed. In addition a new APD structure (HI-LO SAM APD) exhibiting superior performance with respect to a conventional SAM APD has been demonstrated. This novel design improves the conventional SAM APD by the addition of an electric field profile resembling that of an Impatt diode. A gain of 50 and a low dark current (InA) have been demonstrated in the same material system. Finally the operation of electroabsorption pin APD\´s is also reported.
