摘要：

A microcavity enhanced photodiode, consisting of an active semiconducting-polymer layer is studied in detail. The photodiode spectral response indicates features which specifically arise from the cavity geometry factors, as expected from the simulation of the optical-field pattern within the cavity. The results indicate the tuning of photodetection energy range far below the band gap of semiconducting polymer along with sizable gain and speed. (C) 2002 American Institute of Physics.
