Research output: Contribution to journalConference articlepeer-review


We have developed a model to study photodetectors monolithically integrated with optical waveguides and we present the feasability of such compact devices. We report the first fabrication of a Ga0.47In0.53As photoconductor associated with a GaAlAs/GaAs rib waveguide grown on semi-insulating GaAs substrate, which needs only 100 μm to detect 90% of the optical signal.
