在过去的二十年中，碳化硅（SiC）的体、同质外延和异质外延生长已经取得了许多进展，从而产生了广泛用于高功率和高频应用的电子器件。最近的研究表明，SiC还具有独特的光学特性，可用于新型光子器件。SiC是一种从紫外到红外的透明材料，具有从可见光到中红外的非线性光学特性，是中红外波段的超材料。由于色心产生的SiC荧光可以与单光子发射器相关联，并且可以用作量子计算和通信网络以及量子传感的自旋量子比特。这种优异的电子，光子和自旋电子学特性的独特组合促使研究在量子技术领域开发新型器件和传感器。从这个角度来看，我们强调了SiC科学和技术的进展，当前的趋势和前景，支撑着经典和量子光子器件的发展。具体来说，我们列出了最近为实现高质量光子器件而采取的主要步骤，并概述了SiC目前面临的一些挑战，以确定其作为可行的光子技术的相关性。我们还将专注于其独特的潜力，以弥合经典和量子光子学之间的差距，并在技术上推进量子传感应用。最后，我们将展望光子学、电子学和自旋电子学可能合并的可能的替代应用。
In the last two decades, bulk, homoepitaxial, and heteroepitaxial growth of silicon carbide (SiC) has witnessed many advances, giving rise to electronic devices widely used in highpower and high-frequency applications. Recent research has revealed that SiC also exhibits unique optical properties that can be utilized for novel photonic devices. SiC is a transparent material from the UV to the infrared, possess nonlinear optical properties from the visible to the mid-infrared and it is a meta-material in the mid-infrared range. SiC fluorescence due to color centers can be associated with single photon emitters and can be used as spin qubits for quantum computation and communication networks and quantum sensing. This unique combination of excellent electronic, photonic and spintronic properties has prompted research to develop novel devices and sensors in the quantum technology domain. In this perspective, we highlight progress, current trends and prospects of SiC science and technology underpinning the development of classical and quantum photonic devices. Specifically, we lay out the main steps recently undertaken to achieve high quality photonic components, and outline some of the current challenges SiC faces to establish its relevance as a viable photonic technology. We will also focus on its unique potential to bridge the gap between classical and quantum photonics, and to technologically advance quantum sensing applications. We will finally provide an outlook on possible alternative applications where photonics, electronics, and spintronics could merge.
