We demonstrate packet detection at an optical switch input using an optoelectronic control system which then processes the headers of the packets, and controls the switching according to the header content for both fixed and variable length packets a

Optical threshold functions are a basic building block for alloptical signal processing, and this paper investigates a threshold function design reliant on a single active element. An optical threshold function based on nonlinear polarization rotatio

Because of the low crosstalk of the CrossPoint switch, multiple recirculations are possible. This facilitates simplified time-slot interchange configurations that depend on less fiber-delay lines, and single time-slot granularity to enable a short to

This paper considers the performance of an all-optical packet-switched cross-connect. All-optical header processing and all-optical routing are implemented in the cross-connect architectures. The main metric considered to measure the performance is t

We demonstrate a variable optical delay by using a recirculating loop that is controlled by all-optical signal processing technology. This concept can be utilized in all-optical recirculating buffers. The variable optical delay is realized by using a

Most current lens distortion models use only a few terms of Brown's model, which assumes that the radial distortion is dependant only on the distance from the distortion centre, and an additive tangential distortion can be used to correct lens de-cen

Inverse distortion is used to create an undistorted image from a distorted image. For each pixel in the undistorted image it is required to determine which pixel in the distorted image should be used. However the process of characterizing a lens usin

We demonstrate the design and experimental implementation of an electro-optic control system that is used to detect the arrival of packets at the optical switch input, process the headers of the packets, and control switching according to the header
