摘要

双曲型材料具有非常特殊的光学各向异性,同时具有不同的介电张量分量符号。这种各向异性允许奇异的表面波激发,如双曲声子和等离激子的传播。虽然双曲型材料在亚波长光子学和增强光-物质相互作用方面有很大的应用前景,但它们的自然出现仅限于几种材料,通常伴随着显著的介电损耗和有限的双曲型光谱带宽。本文以PdCoO2和PdCrO2 delafoite过渡金属氧化物为研究对象,展示了独特的双双曲结构:一种位于中红外光谱区声子吸收附近,另一种扩展到可见光范围。两种双曲状态均表现出低耗散和高双曲质量因子的特殊性质。这些结果为delafosite层状金属在亚波长光子学、成像和传感方面的创新应用铺平了道路。

Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals
Hyperbolic materials exhibit a very peculiar optical anisotropy with simultaneously different signs of the dielectric tensor components. This anisotropy allows the propagation of exotic surface‐wave excitations like hyperbolic phonons and plasmon polaritons. While hyperbolic materials hold promise for applications in subwavelength photonics and enhanced light‐matter interactions, their natural occurrence is limited to a few materials, often accompanied by significant dielectric losses and limited hyperbolic spectral bandwidth. Focusing on PdCoO2 and PdCrO2 delafossite transition‐metal oxides, in this paper unique dual hyperbolic regimes are demonstrated:: one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range. Both hyperbolic regimes show exceptional properties including low dissipation and high hyperbolic quality factors. These results pave the way for innovative applications of delafossite layered metals in subwavelength photonics, imaging, and sensing.
