Abstract
Photonic time stretch is a powerful technique in measuring the ultrafast transient signal beyond electronic limits. The bandwidth of time stretch is traditionally limited by a dispersion-induced frequency fading phenomenon. To overcome this limitation, we propose and demonstrate a new implementation of time stretch using phase diversity along with the maximum ratio combining technique. Transient signal measurements at 480 GSample/s with the intrinsic bandwidth 96 GHz are demonstrated.
