摘要:

我们展示了芯片级平顶滤波器在近红外波长使用负折射率光子晶体基于马赫曾德尔干涉仪。在全三维数值模拟的支持下,我们通过实验证明了一种用于工程高通、低通、带通和带阻滤波器的新方法,基于设计的光子带隙频率范围内和远离它的能带图。我们进一步表明,我们的方法可以用来设计滤波器,具有可调谐的多,对于光谱的不同部分和对于不同偏振的电平响应。该配置使得能够确定性地控制用于集成光子电路的滤波器的带宽和抑制比。

英文摘要:

We demonstrate chip-scale flat-top filters at near-infrared wavelengths using negative index photonic crystal based Mach Zehnder interferometers. Supported by full three-dimensional numerical simulations, we experimentally demonstrate a new approach for engineering high-pass, low-pass, band-pass, and band-reject filters, based on designing the photonic band diagram both within the band-gap frequency region and away from it. We further show that our approach can be used to design filters that have tunable multi-level response for different sections of the spectrum and for different polarizations. This configuration enables deterministic control of the bandwidth and the rejection ratio of filters for integrated photonic circuits.
