“…With the evolution of the RCE scheme and tapered-holes structures, a novel model for vertical-mesa PD, as shown in Figure 19d, which is realized based on tapered holes and bottom mirrors, could be used to solve the trade-off between bandwidth and responsivity. For waveguide PDs, the responsivity could be improved by exploiting an SWG high-focused mirror which is made by periodic (or non-periodic) strip or concentric circular SWG bonded at the back of the device (Figure 19f), while the usage of DBR mirrors (Figure 19e) have already been simulated [188] and achieved experimentally [189] showing similar performance for the trade-off.…”

High–speed, high–power photodiodes play a key role in wireless communication systems for the generation of millimeter wave (MMW) and terahertz (THz) waves based on photonics–based techniques. Uni–traveling–photodiode (UTC–PD) is an excellent candidate, not only meeting the above–mentioned requirements of broadband (3 GHz~1 THz) and high–frequency operation, but also exhibiting the high output power over mW–level at the 300 GHz band. This paper reviews the fundamentals of high–speed, high–power photodiodes, mirror–reflected photodiodes, microstructure photodiodes, photodiode–integrated devices, the related equivalent circuits, and design considerations. Those characteristics of photodiodes and the related photonic–based devices are analyzed and reviewed with comparisons in detail, which provides a new path for these devices with applications in short–range wireless communications in 6G and beyond.
