- We want faster and faster computers, and light is the fastest thing in the universe.
- Researchers at Seoul National University and the University of Seoul have developed a programmable photonic circuit architecture that can dynamically control how long light pulses take to travel through a chip, effectively controlling their arrival time.
- Rather than having a fixed delay determined when the device is manufactured, the proposed system can be reconfigured to alter the delay, transmission bandwidth, and even frequency characteristics of an optical signal, hence the “programmable” description.
