Fiber-Optic Crossbar Switch With Broadcast Capability

Reconfigurable free-space optical switching technologies for storage area networks

“…The origins of the optical shutter-based switches come from the optical crossbar switch using the vector-matrix multiplier architecture [05]. The performance and compactness of this kind of switch can be enhanced by adopting a two-dimensional matrix-matrix crossbar architecture.…”

“…According to the requirement of uniform light distribution, all output intensities must be equal: '1'2'3'4 (6) Assuming that the fourth grating has the maximum efficiency l4lmax (7) the diffraction efficiency of other gratings can then be determined by solving equations (2) through (5):…”

<title>All-optical interconnection networks</title>

“…Fibers offer a low cost interconnection technology and they are easy to couple. For example, an optical fiber based 4x4 crossbar switch has been demonstrated to provide a data rate in excess of I Gb/s, with small channel loss [12]. Another noticeable advantage is the low level of cross talk and mutual interference in optical networks, which is due to the absence of stray capacitance, mutual inductance and ground currents generally experienced among electrical paths.…”
