Abstract

The optoelectronic mixer is a critical component in millimeter-wave (MMW) and terahertz (THz) systems, facilitating the integration between optical fiber and wireless communication technologies. This study elucidates the optoelectronic mixing principles of the uni-traveling carrier photodiode (UTC-PD) and design a structure with high modulation bandwidth and low conversion loss. The designed mixer achieves a modulation bandwidth of 28.1 GHz with a conversion loss of 9.5 dB at a local oscillator (LO) signal frequency of 60 GHz. At LO signal frequency of 100 GHz, the modulation bandwidth decreases to 26.8 GHz, with a corresponding conversion loss of 16.4 dB.

高调制带宽和低转换损耗的UTC-PD光电混频器

光电混频器是毫米波（MMW）和太赫兹（THz）系统中的关键部件，促进了光纤和无线通信技术之间的集成。本研究阐明了单行载流子光电二极管（UTC-PD）的光电混频原理，并设计了一种高调制带宽、低转换损耗的结构。设计的混频器在本振（LO）信号频率为60 GHz时的调制带宽为28.1 GHz，转换损耗为9.5 dB。在LO信号频率为100 GHz时，调制带宽降至26.8 GHz，相应的转换损耗为16.4 dB。

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
