We demonstrate a two-element symmetric-connected photodiode array (SC-PDA) for high-power and high-speed applications. A traditional traveling-wave photodiode array (TW-PDA), an SC-PDA, and a single PD with the same epitaxial structure were fabricated and tested. Both the TW-PDA and SC-PDA have higher saturation currents, larger RF power, and better high-power and high-frequency responses than the...
We propose a universal simulating solution to characterize the OIP3 of most kinds of photodetectors using Silvaco TCAD simulation tools. For a normal PIN photodetector and a unitraveling-carrier photodetector, a fine agreement was observed in experimental results and simulation results. We believe that this solution could be useful in designing and optimizing high-power photodetectors.
With the development of optical communication system, the nonlinear saturation characteristics of photodetectors are necessary to consider. We observed the 1-dB compression current as DC photocurrent saturation point under high power illumination in PIN-PDs. Meanwhile, a new method of measuring AC saturated output power in the time domain is proposed. The quantitative relationship between DC saturation...
