Photonic Time-stretch Offers Solution to Ultrafast Analog-to-digital Conversion

Analog-to-digital (A/D) conversion represents the key bottleneck in high performance radar and communication systems. The current trend in electronic receivers is to perform the conversion at microwave frequencies. In the so-called "digital receiver," the A/D conversion is performed at microwave (carrier) frequencies, thus placing stringent requirements on the sampling frequency and input bandwidth of the A/D. It is widely recognized that new concepts leading to major advances in A/D technology are a priority.
