摘要

我们提出了一种集成了滤波器的新型硅双工器，用于300 ghz频段的频分复用。该双工器包括一个由无包层硅线组成的定向耦合器、一个基于光子带隙的低通滤波器和一个基于频率相关弯曲损耗的高通滤波器。这些集成滤波器能够抑制串扰，并在40 GHz范围内提供> - 15 dB隔离，这对太赫兹范围的无线通信应用非常有益。我们已将该双工器用于300 ghz和335 ghz信道的同时无差错无线传输，总数据速率为36 Gbit/s。

300-GHz-band diplexer for frequency-division multiplexed wireless communication

SUMMARY We propose a novel silicon diplexer integrated with filters for frequency-division multiplexing in the 300-GHz band. The diplexer consists of a directional coupler formed of unclad silicon wires, a photonic bandgap-based low-pass filter, and a high-pass filter based on frequency-dependent bending loss. These integrated filters are capable of suppressing crosstalk and providing >15 dB isolation over 40 GHz, which is highly beneficial for terahertz-range wireless communications applications. We have used this diplexer in a simultaneous error-free wireless transmission of 300-GHz and 335-GHz channels at the aggregate data rate of 36 Gbit/s.
