Abstract

A versatile angled fiber coupling platform for magnesium fluoride whispering gallery mode resonators is used to investigate nonlinear frequency conversion across 1.5 and 2

μ m

bands. We characterize MgF

_{2}

microcavities of varying sizes (4.3 mm, 1.9 mm, and 0.73 mm in diameter), achieving quality factors up to

2 \times 1 0^{9}

1.55 μ m

and

5 \times 1 0^{8}

1.94 μ m

. In the telecom regime, we observe rich nonlinear phenomena including Kerr comb generation, Brillouin lasing, and Raman lasing. Extending to the 2

μ m

band, we demonstrate four-wave mixing in a sub-millimeter cavity, highlighting the platform’s potential for the 2

μ m

band mid-infrared nonlinear optics.

用于 1.5 和 2μm 波段非线性光学的成角度光纤耦合 MgF2 微腔

我们利用氟化镁耳语画廊模式谐振器的多功能斜角光纤耦合平台来研究 1.5 和 2 μm 波段的非线性频率转换。我们对不同尺寸（直径分别为 4.3 毫米、1.9 毫米和 0.73 毫米）的 MgF2 微腔进行了表征，在 1.55 微米波段和 1.94 微米波段分别实现了高达 2×109 和 5×108 的品质因数。在电信系统中，我们观察到丰富的非线性现象，包括克尔梳生成、布里渊激光和拉曼激光。在扩展到 2 μm 波段时，我们演示了亚毫米波腔中的四波混合现象，突出了该平台在 2 μm 波段中红外非线性光学方面的潜力。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
