Abstract :
The bandwidth limitation of a high-frequency analogue-to-digital (A/D) conversion technique based on photonic time-stretch is investigated. Single-sideband modulation of the electrical input signal is proposed to avoid this limitation. This technique is promising for A/D conversion of ultrafast signals (>100 Gflops)
