Photonic ADCs have removed the bottlenecks of bandwidth limitations and timing jitter of electronic analog-to-digital converter (ADC)

photonic ADC

The performance of digital receivers used in modern military radar, communication, and surveillance systems is often limited by the performance of the analog-to-digital converter (ADC) used to digitize the received signal. Ultrafast ADCs are critical in military applications such as…...
