Abstract

For future photonics devices, in addition to realizing improved performances at high baud rates, key factors that need to be addressed include high-density integration and the ability to realize miniaturization. High-baud rate optical devices that work at 40–100 Gbps in on-off-keying (OOK) systems have been reported [1]. A 3-dB bandwidth over 20–70 GHz band has also been reported; however, in this case, high-baud rate photonic intergradations were not considered. In this paper, in order to consider large-scale integration, we report a new ultra-broadband photodetector (PD) module beyond 110 GHz without any bias circuits.
