Optical Cross Connect Switch Based on Tip/Tilt Micromirrors in a White Cell
نویسندگان
چکیده
We present a new approach to optical interconnections, based on microelectromechanical system tip/tilt mirror technology and the White cell. This is a free-space approach in which many beams circulate simultaneously in the device, each beam forming a unique spot pattern on the micromirror array. On each bounce, each beam can be switched to any of several White cells, each of which has a different effect on the spot pattern. By appropriate combinations of these White cells, any input beam can be directed to any output. A simple proof-of-concept prototype has been demonstrated, and output coupling loss addressed.

Reconfigurable Photonic Switch Based on a Binary System Using the White Cell and Micromirror Arrays
We describe an optical switch for use in crossconnects. It is a free-space device, based on multiple bounces in a pair of White cells sharing a spatial light modulator at one end. In a companion paper, we described various polynomial cells, in which the number of outputs was proportional to the number of bounces raised to some power. In the binary device described here, the number of possible o...

An ultra-compact optical true time delay device is demonstrated that can support 112 antenna elements with better than six bits of delay in a volume 16”x5”x4” including the box and electronics. Free-space beams circulate in a White cell, overlapping in space to minimize volume. The 18 mirrors are slow-tool diamond turned on two substrates, one at each end, to streamline alignment. Pointing accu...

We present a novel optical metro node architecture that exploits the Wavelength Division Multiplexing (WDM) optical cross-connect nodes for interconnecting network elements, as well as computing and storage resources. The photonic WDM cross-connect node based on semiconductor optical amplifiers (SOA) allows switching data signals in wavelength, space, and time for fully exploiting statistical m...
متن کاملCompact Matrix-Switch-Based Hierarchical Optical Path Cross-Connect with Colorless Waveband Add/Drop Ratio Restriction
We propose a compact matrix-switch-based hierarchical optical cross-connect (HOXC) architecture that effectively handles the colorless waveband add/drop ratio restriction so as to realize switch scale reduction. In order to implement the colorless waveband add/drop function, we develop a wavelength MUX/DMUX that can be commonly used by different wavebands. We prove that the switch scale of the ...
متن کاملOptical Cross-Connect Switch Architectures for Hierarchical Optical Path Networks
This paper proposes new switch architectures for hierarchical optical path cross-connect (HOXC) systems. The architectures allow incremental expansion of system scale in terms of the number of input/output fiber ports, wavebands, and optical paths per waveband. These features assure the cost-effective introduction of HOXCs even at the outset when traffic volume is not so large. Furthermore the ...
