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.
