| Popis: | PUBLISHED In this paper, the polarization response of a GaAs based twophoton absorption microcavity photodetector has been studied. The deviation in the dependence of the detector response from that of bulk GaAs is shown to be due to the birefringence of the cavity. A theoretical model based on the convolution of the cavity birefringence and the polarization dependence of two-photon absorption in GaAs is described and shown to match the measured polarization dependence of the microcavity detector very well. The authors would like to thank Dan Kilper of Bell Laboratories, Crawford Hill, for helpful discussions.
