The ever-increasing bandwidth requirements of modern datacenters have led researchers to propose networks based upon optical circuit switches, but these proposals face significant deployment challenges. Expand

We present Opera, a dynamic network that delivers latency-sensitive traffic quickly by relying on multi-hop forwarding in the same way as expander-graph-based approaches, but provides near-optimal bandwidth for bulk flows through direct forwarding over time-varying source-to-destination circuits.

The bandwidth and latency requirements of next-generation datacenter networks stress the limits of CMOS manufacturing. Expand

Optical switching may be instrumental in meeting the cost, power, and bandwidth requirements of future data center networks, but its widespread deployment has a number of technical challenges associated with its circuit-switched characteristics. Expand

We present a first principles analysis of the theoretical scaling limits of transparent nonblocking optical switches based on MEMS electrostatic tilt mirror devices that scale as a function of switch port count, crosstalk, and insertion loss. Expand

We show a spatially variant deconvolution process11,12 that uses focal swept images to extend the depth-of-focus of a For further information: Send correspondence to Stephen J. Olivas. Expand

We present a first-principles analysis of the scaling of switch response speed as a function of port count, crosstalk, and insertion loss, based on physical optics and kinematics of canonical MEMS tilt mirror switch structures. Expand
