Since the instability and uncertainty of optical frequency standards have achieved the level of 10−18, and since the locking time of these frequency standards has become much longer, it is appropriate and necessary to build more practical optical frequency standards. Here we propose a compact design of a transportable Calcium optical frequency standard with the purpose of realizing a long time running optical clock. The design consists of an electronic cabinet and an optical cabinet. The total volume designed is 1.2 m3, with the electronic cabinet 0.8 m3and the optical cabinet 0.4 m3. It is designed to achieve a short term instability of $5times 10^{-14} tau^{-1/2}$ (1–1000s) and a mean time between failures (MTBF) of 8 hours. It may have the potential to be used as an optical timekeeping clock with the long term instability and MTBF optimized.

A low phase noise and highly stable 10 GHz RF signal generation system based on a sub-harmonic injection locked optoelectronic oscillator (OEO) is proposed and experimentally demonstrated. By externally injecting a sub-harmonic of the 10 GHz free-running OEO to the OEO loop, the phase noise at 10 Hz offset of the 10 GHz oscillation RF signal is reduced by 40 dB when compared with the free-running OEO. The influence of the power of the injection RF signal on the phase noise performance of the injection locked OEO is also experimentally investigated.

Self-frequency stabilization of the repetition rate of an optical frequency comb using a short-path-length interferometer can be used to generate ultra-low phase noise microwaves. Moreover, this technique is compatible is photonic integration, indicating a pathway towards a chip-scale low-phase-noise microwave frequency source. Separately, difference-frequency stabilization allows ultra-low phase noise microwave generation without carrier-envelope phase locking. In this work, we evaluate the challenges in implementing a difference-frequency stabilization scheme with a short-path-length-interferometer. We find that the combination of a short-path-length and lower frequency multiplication factor will exacerbate electronic noise contributions, influence the ability of the feedback loop to achieve lock. We also find that dispersion management is essential to generating usable error signals for single-mode fiber delay lines that are longer than approximately 4 m.

While sinusoid signal sources are used whenever low phase noise is required, conversion to a square wave-form is necessary when interfacing with digital circuits. Although have been analyzed a few times in various context, to the best knowledge of the author, there is no complete treatment and explanation of all noise sources within a sine-to-square converter. We attempt to give a quantitative, predictive and physically based noise model of sine-to-square converters without fitting parameters other than those imposed by the circuit itself.

Low loss orthogonal frequency coded (OFC) surface acoustic wave (SAW) correlator filters are demonstrated for use in conjunction with simultaneous transmit and receive (STAR) radios. Single phase unidirectional transducers (SPUDTs) are used to decrease insertion loss of conventional SAW correlators to facilitate use in the transmitter and receiver of STAR radios.

This paper reports on the development of a highly stable miniaturized Oven Controlled Crystal Oscillator (OCXO) in the size of 9.7 × 7.5 mm consisting of heater-embedded ceramic package. The embedded heater layer establishes a symmetrical thermal field to achieve good temperature uniformity, which maintains the oven stability and reduce the power consumption. In addition, the SC-cut crystal is utilized for the proposed miniaturized OCXO to further improve the temperature stability, aging, and phase noise. As a result, this 9.7 × 7.5 mm OCXO has achieved temperature stability of ±3 ppb across −40 to 85 °C. Furthermore, we also demonstrated the proposed miniaturized OCXO could be complied with Stratum 3E requirements.

The MeerKAT radio telescope under construction in South Africa is required to tag the arrival time of a signal to within 10 ns of Coordinated Universal Time (UTC). The telescope has a local maser clock ensemble, compared to UTC by dual-band GPS receivers, and transferred to the digitizers of the array by an optical fiber system. In order to verify the accuracy of the end-to-end time tagging of samples, a portable instrument was constructed that transmits a periodic time signal. This GPS time pulse radiator (GTR) is mounted 10 m away from the telescope L-band feed horn, and radiates a broadband signal of −20 dBm. The signal is modulated by turning off at each UTC second, using the 1PPS output of a GPS receiver. The recorded voltage stream of the telescope is searched for the time signal and the corresponding timestamp compared to its expected value. While less accurate than the masers and dual-band GPS, this technique is simple and the instrument is easily characterized. Laboratory tests of the GTR showed its RF pulse to be at $1.65pm 0.1 mu mathbf{s}$ after the UTC second. Tests on the telescope revealed a $13.0pm 0.3 mu mathrm{s}$ deviation from the expected timestamp value. This was later found to be due to a buffer in the digitizer FPGA, and confirmed by pulsar timing. The GTR concept allows simple, independent testing of a radio telescope pulsar timing system. Future work is planned to improve the shape of the transmitted signal, to study GPS timing errors and correction techniques, and to process the received data using a more standard pulsar timing pipeline.
南非正在建设的MeerKAT射电望远镜被要求将信号的到达时间标记在协调世界时(UTC) 10纳秒以内。望远镜有一个本地脉泽时钟集合,通过双频GPS接收器与UTC相比较,并通过光纤系统传输到阵列的数字化仪。为了验证样品端到端时间标记的准确性,构建了一种传输周期时间信号的便携式仪器。该GPS时间脉冲辐射器(GTR)安装在距离望远镜l波段馈电喇叭10 m处,辐射−20 dBm的宽带信号。信号通过在每个UTC秒关闭来调制,使用GPS接收器的1PPS输出。从望远镜记录的电压流中寻找时间信号,并将其与期望值相比较,得到相应的时间戳。虽然不如脉泽和双频GPS精确,但这种技术很简单,仪器很容易表征。实验室测试表明,GTR的射频脉冲在UTC秒后为$1.65pm 0.1 mu mathbf{s}$。对望远镜的测试显示,与预期的时间戳值有13.0pm 0.3 mu mathm {s}$的偏差。后来发现这是由于数字化仪FPGA中的缓冲,并通过脉冲星定时证实。GTR概念允许对射电望远镜脉冲星计时系统进行简单、独立的测试。未来的工作计划是改进传输信号的形状,研究GPS授时误差和校正技术,并使用更标准的脉冲星授时管道处理接收到的数据。

As an ultra-sensitive mass sensing device, quartz crystal microbalance (QCM) is widely used in gas phase and liquid phase. Previous research reported a novel theoretical model and a new method to separate measurement of density and viscosity of liquid only using a single QCM, based on the analysis of frequency response at room temperature. In this paper, current experimental results demonstrate the method for measuring properties of liquid by using a single QCM is valid at different temperatures.
