Reconfigurable optical interconnects use VCSELs

Optical switches that could form the basis for future networks are being developed by researchers at the University of New Mexico (UNM, Albuquerque, NM). Engineers at the UNM Center for High Technology Materials designed several different types of switches, each time integrating verticalcavity surfaceemitting lasers (VCSELS) with elements such as heterojunction phototransistors (HPTs) and heterojunction bipolar transistors (HBTs). By cascading layers of processing planes, each with a reconfigura
