摘要：

We examine the optical switching characteristics in vertical cavity surface-emitting laser-type vertical-to-surface transmission electrophotonic devices (VC-VSTEPs) with a pnpn structure. It is theoretically and experimentally demonstrated that both optical input/output characteristics are strongly influenced by the structure of the vertical cavity. With improvements in optical power output due to laser oscillation, optical switching speed is enhanced by two orders of magnitude compared to spontaneous emission-type VSTEPs. A 20-mu-m-square VSTEP with an optimized vertical cavity structure demonstrates a low optical switching energy of 2.2 pJ with a switching time of 10 ns, as low as spontaneous emission-type VSTEPs.
