Abstract

In this article, we illustrate the working principle of optoelectronic mixing for uni-traveling-carrier photodetector (UTC-PD). As a result of the combined influence of local oscillators (LO) and bias modulation signals (RF), the velocity and concentration of photogenerated electrons in the depletion region exhibit mixing components with frequencies of \(|{f}_{LO}\pm {f}_{RF}|\). The optoelectronic mixing signal is primarily generated by these two components, and its peak value is determined by the concentration of photogenerated electron. Moreover, the cliff layer can greatly enhance the output power of the mixed frequency signal, since it allows more photogenerated electrons to be transmitted to the depletion region.

UTC-PD 的光电混合原理和最佳工作条件

本文阐述了单漂移载流子光电探测器（UTC-PD）的光电混合工作原理。由于局部振荡器（LO）和偏置调制信号（RF）的共同影响，耗尽区的光生电子速度和浓度呈现出频率为 \(|{f}_{LO}\pm {f}_{RF}|\) 的混合分量。光电混合信号主要由这两个分量产生，其峰值由光生电子的浓度决定。此外，峭壁层可以大大提高混频信号的输出功率，因为它允许更多的光生电子传输到耗尽区。

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
