Abstract

An optical processing device is arranged to separate a plurality of optical signals received at an input into a plurality of separate output signals, the device comprising: (a) an optical chip arranged to receive and separate the plurality of optical signals; (b) light sensing means comprising means comprising at least one array of light sensors mounted on a common support, the support being mounted on or adjacent the chip such that the light sensors receive the plurality of output optical signals directly from the chip; and (c) an electrical connector comprising a first array of electrical contacts electrically connected to the array of light sensors, a second array of electrical contacts, and a plurality of flexible electrical conductors electrically interconnecting the first and second arrays of electrical contacts such that the light sensors may be electrically connected to electronic circuitry external to the device.
