Abstract
50GHz bandwidth photodiodes. attaining a compression pint of +12dBm, have b een fabricated. The structure design allows an almost complete absorption a t 25 mum, corresponding to 0.5A/W responsivity and gives a polarisation dep endence as low: as +/-0.1dB. These components have been realised with a low -cost technology including etched waveguide input facet. antireflection coa ting on wafer and cleaving V-grooves.
