Abstract

novel dual-purpose vertical-cavity optoelectronic component (VCOC), functioning either as a laser or a detector, is reported. The device is formed by modifying a conventional vertical-cavity surface-emitting laser so that it can additionally operate as an efficient detector. The modifications to the device, in order to improve photodetection, are achieved by etching its top facet. Avalanche operation under reverse bias is demonstrated for the first time in such a dual purpose component. In order to assess the overall device performance for communication applications, a bi-directional, half-duplex link is established in which a VCOC used as a source transmits signals to one used as a detector at bit rates up to 2 Gb/s
