Perspectives

David Walba

Present and future information technology requires ever faster data transmission rates, but conventional circuitry has serious limitations. In his Perspective, Walba describes a new generation of electrooptical devices based on liquid crystals. These 'spatial light modulators' can be integrated with silicon circuits to offer compact, ultrafast optical processing of data.
