Abstract
High-speed detectors are useful in a wide range of applications, including Lidar, fiber optics, and millimeter-wave optoelectronics. The fundamental limits of detector performance are the transit time across the depletion region and the rc time constant of the diode capacitance and the load resistor.1 Making the absorbing layer thinner makes the transit time lower, but it raises the capacitance, whereas thicker detectors have low capacitance but high transit times. This fundamental trade-off is resolved in an optimum thickness that is dependent on detector diameter and material constants.
