论文摘要
基于微孔子的光学频率梳子（MicroComb）具有革新雷达和通信应用中频率合成器的准确性的潜力。但是，低噪声微型尸体生成的基本极限，尤其是在低尺寸，重量，功率和成本（SWAP-C）软件包中。在这里，我们通过证明自动的交钥匙微型炸弹来解决此限制，在紧凑的设置尺寸为85毫米 * 90毫米 * 25毫米的紧凑型设置尺寸中，运行接近其低量子限制相位噪声。在自我注射锁定方案中，在二极管 - 泵箱中，高质量的纤维纤维纤维纤维谐振器（FFPR），Q高达4.0 * 10^9，是低量子噪声和泵噪声限制的关键。在100 Hz，-106和-125 dbc/hz时为-80和-105 dbc/hz的低相位噪声分别在10.1 GHz和1.7 GHz重复频率下，在10 kHz时为1 kHz，-133和-148 dbc/hz。凭借同时自动的交钥匙，低噪声和直接二极管泵的功能，我们的Microcomb可以用作低交换-C的低噪声频率合成器，从而将其用作现场可部署性。
Microresonator-based optical frequency comb (microcomb) has the potential to revolutionize the accuracy of frequency synthesizer in radar and communication applications. However, fundamental limit exists for low noise microcomb generation, especially in low size, weight, power and cost (SWaP-C) package. Here we resolve this limit, by the demonstration of an automated turnkey microcomb, operating close to its low quantum-limited phase noise, within a compact setup size of 85 mm * 90 mm * 25 mm. High quality factor fiber Fabry-Perot resonator (FFPR), with Q up to 4.0 * 10^9, is the key for both low quantum noise and pump noise limit, in the diode-pump case in a self-injection locking scheme. Low phase noise of -80 and -105 dBc/Hz at 100 Hz, -106 and -125 dBc/Hz at 1 kHz, -133 and -148 dBc/Hz at 10 kHz is achieved at 10.1 GHz and 1.7 GHz repetition frequencies, respectively. With the simultaneous automated turnkey, low-noise and direct-diode-pump capability, our microcomb is ready to be used as a low-noise frequency synthesizer with low SWaP-C and thus field deployability.
