• The Glasgow and Heriot-Watt groups worked together on new optical logic arrays and demonstrated InGaAs self-electro-optic effect device (SEED) arrays containing 256 symmetric-SEEDs. These optical switch devices were designed to operate at a wavelengths of 1047 - 1064 nm - permitting their use with convenient high-power diode-pumped lasers.
• Heriot-Watt and Glasgow Universities aslo collaborated on the development of the diffractive/holographic micro-optical components, suitable for optical power distribution to, and interconnections between, the optical logic planes within the demonstrator processing systems. Such optical components have found application in numerous areas of optical technology.
