Title: The Innovations of Henry H. Yaffe
Introduction
Henry H. Yaffe is a notable inventor based in Dunwoody, Georgia, with a remarkable portfolio of 15 patents. His contributions to the field of optical technology have significantly advanced the capabilities of data transmission and communication systems.
Latest Patents
One of Yaffe's latest patents is the Dense WDM optical multiplexer and demultiplexer. This invention allows for the efficient demultiplexing of optical channels supplied to first and second optical fibers via an optical splitter. Low loss interference filters are coupled to the fibers to select respective groups of channels. Each group is then demultiplexed with sub-demultiplexers into individual channels, which are sensed by corresponding photodetectors. Despite the optical splitter introducing some power loss, the overall power loss is significantly less than that of conventional n-channel demultiplexers. This innovation enables the demultiplexing and detection of large numbers of channels, exceeding forty.
