摘要

我们展示了一个悬浮锗波导平台，在7.7µm波长下的传播损耗为5.3 dB/cm，在自由空间光通信和吸收传感方面具有潜在的应用前景。此外，我们的模拟显示低损耗传输至~15 μ m波长。

Suspended germanium waveguides with metamaterial lateral cladding for mid-infrared integrated photonics

We demonstrate a suspended germanium waveguide platform with a propagation loss of 5.3 dB/cm at a wavelength of 7.7 µm, with potential applications in free-space optical communications and absorption sensing. Furthermore, our simulations show low-loss propagation up to ~15-µm wavelength.
