Abstract
A transceiver for use in a bidirectional optical communication link over a multimode channel is provided. The transceiver includes a single transverse mode light source in a transmitter. A waveguide or fiber based bidirectional coupler projects the transmitter mode to the high modes of the multimode channel. A detector coupled to predominantly all the modes of the channel via the waveguide or fiber based bidirectional coupler.
