Abstract
The authors have designed and fabricated oxide-apertured photodetectors Int egrated with vertical cavity surface emitting lasers (VCSELs). The photocur rent originating from spontaneous emission is suppressed by more than a fac tor of 10 in this integrated photodetector owing to the use of nonradiative recombination at the GaAs/oxide interface. In addition, the unavoidable in ternal loss from the detector is minimised by locating the GaAs detection l ayer as far as possible from the VCSEL cavity.
