摘要

我们提出了一种基于集成在等离子体微腔中的掺铁InGaAs层的太赫兹(THz)频域光电混频器。我们表明，在1550 nm波长照明下，这种结构允许在220 nm薄的InGaAs吸收器中具有超过70%的吸收效率和非常高的Roff/Ron >1000。这导致由1550纳米激光器驱动的太赫兹混频器在300 GHz时显示低至~ 30 dB的转换损失。因此，该设计非常有希望应用于高数据速率无线电信，w-THz光谱仪或光子学支持的THz频谱分析仪中的接收器。

Photonic THz mixers based on iron-doped InGaAs embedded in a plasmonic microcavity

We present an optoelectronic mixer for the terahertz (THz) frequency-domain based on an iron-doped InGaAs layer integrated in a plasmonic microcavity. We show that this structure, under 1550-nm-wavelength illumination, allows for more than 70% absorption efficiency in a 220 nm-thin InGaAs absorber and very high Roff/Ron >1000. It leads to THz mixers driven by 1550-nm lasers showing conversion loss as low as ∼30 dB at 300 GHz. Therefore, this design is very promising for application as receivers in high-data-rate wireless telecom, in cw-THz spectrometers, or in photonics-enabled THz spectrum analyzers.
