Optical circuit switching may be instrumental in meeting the cost, energy, and aggregate bandwidth requirements of future data center networks. However, conventional MEMS beam-steering cross-connects cannot provide submillisecond switching with the p

The Lightwave Energy-Efficient Datacenter (LEED) project within the ARPA-e ENLITENED program is developing novel energy-efficient multichannel lightwave networks. These networks are enabled by a new optical “rotor” switch that can reconfigure the

We describe a panoramic camera using one monocentric lens and an array of light field (LF) sensors to capture overlapping contiguous regions of the spherical image surface. Refractive sub-field consolidators divide the light before the image surface

Fiber-coupled image sensors have attracted interest in recent years for high-resolution conformal image transfer, including mapping of the spherical image surface of a monocentric wide-angle lens to one or more flat focal plane sensors. However, imag

We investigate partially configurable optical circuit switches as a means to circumvent the physical and control layer scaling challenges of optical crossbar switches. We present the optical design and characterization of a prototype partially config

Transparent optical circuit switching can improve the aggregate bandwidth, scalability, and cost of data center networks provided, it can meet the performance requirements on switching speed, port count, and optical efficiency. Here, we examine the t

Light field (LF) capture and processing are important in an expanding range of computer vision applications, offering rich textural and depth information and simplification of conventionally complex tasks. Although LF cameras are commercially availab

We propose a receiver design and simulation that optimizes a Si microlens array with micro-optic injection structures to selectively couple light into a waveguide and then to an edge-mounted detector to couple 2.5Gbps modulated input.

We describe a monocentric wide-field camera that corrects field curvature by light field processing, showing a contiguous multi-sensor design, and results from a relay-imaged testbed that sequentially captures a 72 MPixel 138° light field panorama.
