Abstract

We demonstrate the acousto-optic modulation of a hybrid-lattice hollow core fiber (HL-HCF) for the first time. For many years, optical fibers with reduced diameters have been the main solution to increase the interaction of acoustic and optical waves. However, the high drive voltages and large modulator components still employed drastically affect the efficiency and miniaturization of these devices. Here, we experimentally show that combining Kagomé and tubular lattices in HL-HCFs allows for enhancing the amplification of the acoustic waves and the modulation of the guided optical modes, thus providing high modulation efficiency even when using a fiber with a

$240~\mu $

m diameter. To the best of our knowledge, the measured HL-HCF’s modulation efficiency (1.3 dB/V) is the highest compared to devices employing reduced diameter fibers. Additionally, we demonstrate a compact acousto-optic modulator with driver dimensions smaller than the HL-HCF diameter. Overall, our results show a promising alternative to solve the compromise of speed, efficiency, and compactness for integration with microscale all-fiber photonic devices.

基于混合晶格中空芯纤的高效紧凑型声光调制器

我们首次展示了混合晶格空芯光纤（HL-HCF）的声光调制。多年来，缩小直径的光纤一直是提高声波和光波相互作用的主要解决方案。然而，仍然采用的高驱动电压和大型调制器元件严重影响了这些设备的效率和小型化。在这里，我们通过实验证明，在 HL-HCF 中结合卡戈梅晶格和管状晶格可以增强声波的放大和引导光学模式的调制，因此即使使用直径为 240~\mu $ m 的光纤也能提供很高的调制效率。据我们所知，所测量的 HL-HCF 的调制效率（1.3 dB/V）是采用小直径光纤的设备中最高的。此外，我们还展示了一种驱动器尺寸小于 HL-HCF 直径的紧凑型声光调制器。总之，我们的研究结果表明，在解决与微尺度全光纤光子器件集成的速度、效率和紧凑性之间的折衷问题方面，这是一种很有前途的替代方案。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
