均匀介质中的宽带布拉格现象

Broadband Bragg phenomenon in a uniform medium

Martin W. McCall, Stefanos Fr. Koufidis

摘要:

布拉格反射的一个新的机制被确定,一个,值得注意的是,发生在一个均匀的介质,并依赖于介质的参数的谐振调谐。由于均匀性,反射在很宽的波长范围内,很像金属,但它是偏振依赖的:一个圆形状态被反射,而另一个被透射。因此,这种介质可以提供宽带、低损耗的偏振分配器/组合器。对所需参数的评估表明,制造在当前超材料技术的范围内。通过外部调节介质的参数,高效的光调制器是可能的,具有跨光学、光电子学和光子学的潜在应用。

英文摘要:

A new mechanism of Bragg reflection is identified, one that, remarkably, occurs in a uniform medium and relies on resonant tuning of the medium's parameters. Due to uniformity, reflection ensues over a broad wavelength range, much like a metal, but it is polarization dependent: one circular state is reflected, whilst the other is transmitted. Such a medium can thus provide a broadband, low-loss polarization divider/combiner. Assessment of the required parameters suggests that manufacturing is within range of current metamaterials technology. By externally regulating the medium's parameters, a highly efficient optical modulator is possible with potential applications across optics, optoelectronics, and photonics.
