论文摘要
频率梳子,宽带光源,其光谱由连贯的离散模式组成,在许多领域都至关重要。在这些领域中,微型化频率梳将是一个重大的进步,从而使基于频率的设备的部署用于不同的测量和光谱应用。我们演示了基于二极管激光器的频率梳子发生器。这些激光二极管是简单,电泵的,便宜且易于制造的。每个芯片都包含数十个二极管激光梳子。我们测量二极管频率梳子的时间域输出,以揭示负责梳状频谱的基本频率动力学,在同一芯片上进行两个设备的分子气体进行双梳谱图,并证明这些梳子可以电池供电。
Frequency combs, broadband light sources whose spectra consist of coherent, discrete modes, have become essential in many fields. Miniaturizing frequency combs would be a significant advance in these fields, enabling the deployment of frequency-comb based devices for diverse measurement and spectroscopy applications. We demonstrate diode-laser based frequency comb generators. These laser diodes are simple, electrically pumped, inexpensive and readily manufactured. Each chip contains several dozen diode-laser combs. We measure the time-domain output of a diode frequency comb to reveal the underlying frequency dynamics responsible for the comb spectrum, conduct dual comb spectroscopy of a molecular gas with two devices on the same chip, and demonstrate that these combs can be battery powered.
