Abstract :
We demonstrate linear cascade near-ballistic uni-traveling-carrier photodiodes. Compared with control (a single device), this novel structure exhibits significant improvement in bandwidth-efficiency and saturation-current-bandwidth products. Record-high saturation-current-bandwidth product ( > 6825 mA-GHz, 91GHz) under 50Ω loads can be achieved.
