Abstract: Methods and apparatus are described for optical interconnection. A method includes reconfiguring a free space broadcast interconnection including repositioning a micro electromechanical system mirror. An optical interconnect system comprises: at least two processing elements, each of said processing elements comprising: at least one optical signal transmitter; at least one optical signal receiver on the same support structure as the transmitter; and at least one MEMS mirror to provide the capability of optically connecting the emitter and transmitter.
