An enlightened take on digital logic could spawn a revolution in device development
Field-programmable gate arrays (FPGAs) have revolutionised the electronics industry. As their name implies, they are integrated circuits that can be programmed or reprogrammed by the customer to any required functionality or application after manufacturing - i.e. in the field. Now, the EU-funded FPPAs project is preparing a spin-off company to commercialise its technology that moves from programmable digital logic operations to optical interference for very high-speed analogue operations. The newly christened field-programmable photonic array (FPPA) could revolutionise the market now dominated by almost as many optical circuits for specific tasks as there are applications. An optical programmable chip could reduce design and fabrication costs while ushering in a new era of optical innovation.
