Research output: Chapter in Book/Report/Conference proceedingConference contribution


We present a novel vertical-cavity semiconductor device capable of generating in forward bias optical radiation to pump fluorescent labelling dyes and detecting their fluorescence emission when operated in reverse bias mode. The integration of a partially coherent light source and a sensitive detector within the same semiconductor wafer is a further step toward the realization of optical biochips for DNA analysis and cytometry. The structure and the criteria chosen to design these devices, their emission and detection properties are presented and discussed in detail.
